	  value

externs.h
	- new file, with function declarations not mentioned in other header
	  files.  Included by shell.h.

cpp-Makefile, builtins/Makefile
	- updated the dependencies to include new header files

bashline.c, execute_cmd.c, jobs.c, general.c, mailcheck.c, make_cmd.c,
nojobs.c, parse.y, print_cmd.c, shell.c, subst.c, test.c, trap.c,
variables.c, builtins/common.c, builtins/bind.def, builtins/declare.def,

execute_cmd.c
	- don't bother trying to free the string passed to make_child in
	  the child if the command is not found

bashhist.c, bashhist.h
	- new files with bash interface to the history library.  Moved code
	  from parse.y, shell.c, subst.c to here.

parse.y, bashline.c, shell.c, subst.c, variables.c
	- include bashhist.h

error.c, bashhist.c, bracecomp.c
	- added copyright comment

machines.h
	- changed hpux_8 and hpux_9 entries to #undef USE_GNU_MALLOC
	  because they have the same YP bug as SunOS

				   9/10
				   ----
print_cmd.c
	- fixed the printing of functions declared within functions by
	  making print_function_def and named_function_string responsible
	  for printing the open and close braces and printing the `inside'
	  command rather than overloading print_group_command

builtins/fc.def, builtins/history.def

	- removed from the source tree

				   9/13
				   ----
lib/doc-support
	- new directory for building texindex

lib/doc-support/texindex.c
	- upgraded to version 1.45 from the texinfo-3.1 distribution

documentation/Makefile
	- fixed so that features.dvi would build correctly

variables.c, subst.c, braces.c, flags.c, jobs.c, mailcheck.c, parse.y,
builtins/cd.def, builtins/common.c, lib/readline/history.c,
lib/readline/isearch.c, lib/readline/readline.c
	- removed instances of `index' being used as a variable or
	  structure member

cpp-Makefile
	- pass HAVE_LIMITS_H through to the rest of the build in
	  SYSTEM_FLAGS and LIBRARY_CFLAGS

maxpath.h
	- removed inclusion of `sysdefs.h', since the only reason it was
	  included was to pick up HAVE_LIMITS_H

				   9/14
				   ----
bashhist.h
	- add extern declaration of history_expansion_inhibited, dependent
	  on BANG_HISTORY

execute_cmd.c, builtins/common.c, subst.c, variables.c, parse.y, jobs.c,
error.c, bashline.c
	- moved all extern variable declarations to beginning of file,
	  giving them file scope

execute_cmd.c
	- changed the code so that /dev/null is used as fd 0 for async
	  jobs if the shell itself is not interactive (!interactive_shell)
	  rather than currently interactive (!interactive)

builtins/break.def, builtins/cd.def, builtins/declare.def
builtins/exit.def, builtins/fc.def, builtins/fg_bg.def builtins/hash.def,
builtins/kill.def builtins/read.def, builtins/return.def,
builtins/setattr.def builtins/source.def, builtins/type.def,
builtins/wait.def
	- moved all extern variable declarations to beginning of file,
	  giving them file scope

				   9/15
				   ----

	- change the test to set SCOREL so that it handles SCO v4.2 and
	  above (everything above and including 4.0)

machines.h
	- changed M_OS define of `Solaris' to `SunOS5'; added -DSolaris to
	  SYSDEP_CFLAGS for Solaris 2 systems

				   9/16
				   ----
print_cmd.c
	- make sure cprintf() null-terminates the_printed_command correctly

test.c
	- changed the last two stray stat() calls to test_stat()
	- made test_stat handle emulation of /dev/fd for systems that
	  don't have it: /dev/fd/x returns the result of fstat(x, finfo)

documentation/bash.1
	- added -b to the usage line for the `set' builtin
	- added description of `set -o posix'
	- added -u, -v to the usage line for the `ulimit' builtin
	- added text describing key bindings in ~/.inputrc to the
	  READLINE section

documentation/texinfo.tex
	- upgraded to the latest version from the texinfo-3.1 distribution

documentation/features.texi, lib/readline/doc/rluser.texinfo, 
lib/readline/doc/hsuser.texinfo
	- a major overhaul and expansion

				   9/17
				   ----
bashline.c
	- set rl_vi_comment_begin to "#" when in Posix.2 mode

lib/readline/vi_mode.c
	- set vi mode comment begin character string to "#" by default

				   9/18
				   ----

	- added `set keymap' command to the init file variable setting code

documentation/bash.1, documentation/features.texi
	- added description of `set keymap' command

lib/readline/doc/rluser.texinfo
	- completed description of init file and keybinding syntax

				   9/20
				   ----
variables.c
	- if POSIXLY_CORRECT or POSIX_PEDANTIC are in the initial shell
	  environment, enter `Posix.2 mode'

machines.h
	- define SCO REQUIRED_LIBRARIES as `-lc_s -lc -lPW' to pick up
	  the functions in libc and libPW from libc (e.g. rename)


				   9/21
				   ----
execute_cmd.c
	- fixed X_BIT macro to protect its argument with parens in the
	  macro body

maxpath.h
	- include sys/param.h on Dynix machines if MAXPATHLEN is not
	  defined after including limits.h

general.c
	- moved the inclusion of <signal.h> on Posix.1 systems up with the
	  rest of the includes

shell.c, lib/readline/complete.c, lib/tilde/tilde.c
	- don't extern declare getpwuid on Dynix machines

lib/readline/history.c
	- make sure strlen() is cast to int whenever used in a comparison

				   9/23
				   ----
lib/readline/readline.c
	- changed rl_call_last_kbd_macro to disallow recursive macro
	  execution

				   9/26
				   ----
bashline.c
	- free rl_vi_comment_begin before assigning to it; make sure to
	  savestring() what we assign to it

				   9/28
				   ----
lib/readline/search.c
	- in noninc_search, make the ^W and ^U bindings closer to what
	  Posix.2 specifies.  (The ^W binding still uses unix_word_rubout,
	  which uses whitespace as the word boundary.  This is what
	  ksh-88 does, too.  Posix.2 says to use punctuation characters
	  as word boundaries also.)

lib/readline/vi_mode.c
	- fixed a bug in rl_vi_delete_to which caused c[wW] to delete one
	  extra character when there were multiple spaces between words.
	  Made the same change to rl_vi_change_to() and rl_vi_yank_to().

lib/readline/complete.c
	- fixed quoted substring completion so that `\' can quote the
	  quote character
	- fixed the quoted string completion mechanism by doing the
	  following:
		o quoted word break characters do not break words for the
		  completer, so `"abcde"/xhy' no longer sends `/xhy' to
		  the rest of the completion code
		o quotes are stripped after the application-specific
		  completion function is attempted if filename completion
		  is about to be performed.  If needed, they are added
		  back later.  This has the benefit of removing unneeded
		  quotes.

				   9/29
				   ----
siglist.h
	- ICL DRS6000s need sys_siglist to be defined as _sys_siglist

machines.h
	- take the define of sys_siglist out of the DRS6000 entry
	- added summary of available definitions for SYSDEP_CFLAGS
	- added new SYSDEP_CFLAGS variable: HAVE_GETPW_DECLS to isc386, sgi,
	  Linux, Dynix descriptions
	- changed isc386 description: added ISC_SYSDEPS to make the
	  SYSDEP_CFLAGS lines a little cleaner

shell.c, lib/tilde/tilde.c, lib/readline/complete.c
	- now uses HAVE_GETPW_DECLS define

lib/tilde/tilde.c
	- removed references to getpwent(), since it's not called
	- add extern declaration for getpwnam()

lib/readline/complete.c
	- add a __STDC__ definition for getpwnam() for isc386 machines

cpp-Makefile
	- updated the dependencies: bashhist.h, bashansi.h, dependencies
	  on the library include files

				   9/30
				   ----
mailcheck.c
	- cleaned up the name space by making functions not used by other
	  files static
	- took out redundant test in check_mail after the goto next_mail_file

variables.c
	- cleaned up the code a bit by removing unnecessary { ... } pairs
	  enclosing some code blocks
	- check for $IGNOREEOF at startup, call sv_ignoreeof if imported

parse.y
	- new variable `ignoreeof', non-zero if we are ignoring EOF, used
	  in handle_eof_input_unit -- keeps us from looking up $IGNOREEOF
	  and $ignoreeof on every EOF character

subst.c
	- sv_ignoreeof now sets or clears `ignoreeof'

flags.h
	- changed flags_alist `name' member to be a char, since we only
	  ever use one character
	- added FLAG_UNKNOWN to be returned by find_flag, since (int *)-1
	  is not portable, and (int *)0 is just as good a value

flags.c
	- changed find_flag, change_flag_char, change_flag, to take a
	  char as a parameter rather than a char * because we only use
	  one char and this is faster

builtins/set.def
	- changed calls to find_flag to pass a char instead of a char *

shell.c, jobs.c, builtins/set.def
	- changed instances of change_flag_char to change_flag, since the
	  two are now equivalent

cpp-Makefile
	- added BUILTIN_OBJS, made BUILTINS_LIB depend on them
	- added dependencies for builtin objects on builtin .def files
	- otherwise tightened up the dependencies

				   10/1
				   ----
support/mksysdefs
	- handle SGI Irix 5.x by making SYSDEF="Irix5"

parse.y
	- made init_yy_io a void function

input.h
	- moved extern function declarations for parse.y and input.c to
	  this file from externs.h

shell.c
	- include input.h unconditionally, now that it has extern function
	  declarations
	- check for $POSIX_PEDANTIC at shell startup, set posixly_correct
	  if found

make_cmd.c
	- include input.h for the extern function declarations

execute_cmd.h
	- new file, with extern declarations from execute_cmd.c

subst.c, builtins/type.def, variables.h, builtins/exec.def, builtins/hash.def,
shell.c, buitlins/common.c, execute_cmd.c, mailcheck.c
	- include execute_cmd.h

cpp-Makefile, builtins/Makefile
	- updated the dependencies as a result of the new and changed
	  include files

execute_cmd.h, externs.h, input.h
	- changed to use the __P(()) method of using prototypes for extern
	  functions

nojobs.c
	- include command.h

				   10/5
				   ----
bashline.c
	- make sure test_for_directory frees the filename if stat(2)
	  fails

lib/readline/vi_mode.c
	- fixed the `c' command when used with the following motion
	  commands: `^', `0', `%', `b', `B'.  The cursor was being
	  moved one position too far, resulting in too much erasure

parse.y
	- changed redirection_needing_here_document into a stack of
	  such redirections (redir_stack), indexed by need_here_doc,
	  to handle command lines with >1 redirection, e.g.
		cat <<a; cat <<b
	- new function gather_here_documents to run the redirection stack

shell.c
	- don't import redirection_needing_here_doc; call
	  gather_here_documents() instead

input.h
	- extern declaration for gather_here_documents()

machines.h
	- add OPENDIR_NOT_ROBUST to the SYSDEP_CFLAGS for SunOS 5

				   10/6
				   ----
subst.c
	- removed the unused `preserve_backslashes' and Q_KEEP_BACKSLASH
	  code in expand_word_internal
	- fixed memory leak: free `istring' before longjmping out of a
	  bad substitution
	- fixed memory leak: free `temp' at the bad_substitution label
	- fixed memory leak: free `value' at the bad_substitution label
	- removed all calls to longjmp from expand_word_internal: it now
	  returns a pointer to expand_word_error or expand_word_fatal,
	  and the caller is responsible for cleaning up locally allocated
	  resources and calling longjmp with the appropriate parameter.
	  BY CONVENTION: when one of those distinguished values is returned,
	  the `string' variable has already been freed, so the caller must
	  set it to null or otherwise not free it
	- changed an fprintf (stderr, ...) to report_error in
	  parameter_brace_expand_error

dispose_cmd.c
	- check for word->word being non-null in dispose_word before trying
	  to free it

				   10/8
				   ----
variables.c
	- made new_shell_variable static
	- made set_var_read_only, set_func_read_only, set_var_auto_export,
	  set_func_auto_export, sort_char_array, maybe_make_export_env,
	  put_command_name_into_env void functions

variables.h
	- added declarations for all the missing extern functions

builtins/hash.def
	- include posixstat.h for definition of struct stat to use in
	  function prototype declarations

expr.c                                 
	- renamed local function `assignment' to `expassign' to avoid
	  clashing with the global `assignment' defined in variables.c

builtins/source.def
	- include `execute_cmd.h' to pick up extern function declarations

trap.h
	- protected against multiple inclusion with __TRAP_H__ define
	- added prototypes with __P

				   10/11
				   -----
support/mksysdefs
	- check in /usr/include/ansi and /usr/include/bsd for NeXT 3.x
	  machines

lib/readline/vi_mode.c
	- include rldefs.h

				   10/12
				   -----
test.c
	- changed the `-x' test to call access(2) when AFS is defined,
	  since `stat' doesn't work with AFS

builtins/cd.def
	- added code to dirs_builtin to implement dirs -n and dirs +n

documentation/bash.1, documentation/features.texi
	- updated description of `dirs' builtin

				   10/14
				   -----
lib/readline/bind.c
	- new function _rl_bind_if_unbound, which binds a key sequence to a
	  readline function if that key sequence is unbound

lib/readline/readline.c
	- use _rl_bind_if_unbound to try to bind the arrow keys in
	  init_terminal_io


				  10/15
				  ----- 

lib/readline/display.c
	- laid the groundwork for expanding special characters in
	  readline prompt strings: new function expand_prompt
	- rl_redisplay now has static local prompt variables:
		local_prompt: expanded prompt string after last newline
		local_prompt_prefix: expanded prompt string before last newline
		visible_length: number of visible chars in local_prompt	
		prefix_length: number of visible chars in local_prompt_prefix
	  changed when rl_display_prompt changes

				   10/18
				   -----
lib/readline/display.c
	- new function: rl_expand_prompt, expands the prompt and sets the
	  local display variables to the right values for redisplay.
	- changed rl_redisplay to use the values computed by rl_expand_prompt
	  if rl_display_prompt == rl_prompt and the old expansion code if
	  otherwise (for instance, if rl_display_prompt is set by rl_message)

lib/readline/readline.c
	- new function: rl_get_termcap to retrieve the value of any termcap
	  attribute that readline retrieves
	- made readline_internal static, added appropriate declarations
	- new global library variable: rl_visible_prompt_length
	- added call to rl_expand_prompt in readline() before call to
	  rl_initialize

lib/readline/search.c
	- use rl_visible_prompt_length instead of strlen(rl_prompt) in
	  noninc_search ()

				   10/19
				   -----
execute_cmd.c
	- in execute_command_internal, mark an async job with a forced
	  subshell `( xxx ) &' as no longer an interactive shell, no
	  matter whether or not the original shell was interactive.  This
	  allows jobs to be reaped without notification and fixes a mem
	  `leak' (not really a leak, but the shell keeps increasing the
	  size of the jobs table)

				   10/21
				   -----
machines.h
	- updated the NEC EWS description with hints from Jim Blandy

				   10/23
				   -----

lib/readline/display.c
	- changed expand_prompt so that it understands `escape' characters
	  to mark the beginning and end of a sequence of non-visible
	  characters, and takes these into account when returning the
	  length of the prompt string

lib/readline/readline.h
	- new defines: RL_PROMPT_START_IGNORE and RL_PROMPT_END_IGNORE

				   10/24
				   -----

parse.y
	- removed check for $NO_PROMPT_VARS from decode_prompt_string()

documentation/bash.1
	- removed reference to $NO_PROMPT_VARS

				   10/25
				   -----
machines.h
	- add -lc_s to the AIX/PS2 REQUIRED_LIBRARIES definition

lib/readline/readline.c
	- removed the extra space that rl_yank_nth_arg adds before the
	  yanked string

				   10/26
				   -----
trap.c
	- set_sigint_handler now sets the SIGINT handler to sigint_sighandler
	  only if `interactive' is set, rather than interactive_shell.  This
	  fixes the `". x", then sigint' bug reported by Vasco Pedro.

general.c
	- removed `register' from variable declarations in function prologues
	- some functions now take slightly different arguments:
		delete_element takes a `char *' as the third argument
		find_name_in_list takes a `char **' as the second argument

general.h
	- changed definition of REVERSE_LIST to cast the argument of the
	  call to reverse_list()
	- added prototypes for all extern functions defined in general.c
	- definition of BCOPY for use in general.c and elsewhere

shell.c
	- changed some calls to reverse_list to REVERSE_LIST

shell.h, make_cmd.c, unwind_prot.c, input.c, builtins.h, error.c
	- include command.h before general.h for declaration of WORD_LIST

execute_cmd.c, expr.c, general.c, input.c, shell.c, unwind_prot.c, parse.y
	- changed calls to bcopy to call xbcopy instead, and cast the
	  first two arguments to char *

copy_cmd.c
	- changed calls to bcopy to call BCOPY instead

machines.h
	- new machine definition for IBM AIX/ESA (OSF/1) from Sergio
	  Gelato

support/mksysdefs
	- If `uname -m' returns `ESA', the machine is an IBM ESA

lib/posixheaders/memalloc.h
	- new file, to unify the code to include <alloca.h> if necessary
	  and declare alloca()

config.h, config.h.mini, lib/readline/rldefs.h, lib/readline/history.c,
lib/readline/isearch.c, lib/readline/search.c, lib/tilde/tilde.c
	- changed to include "memalloc.h"

builtins/getopt.c
	- don't include #pragma alloca line on IBM ESA systems
	- include malloc.h rather than alloca.h for AIX/ESA

support/getcppsyms.c
	- new defines to support AIX/ESA

cpp-Makefile, builtins/Makefile, lib/readline/Makefile
	- updated dependency information to include memalloc.h

lib/readline/vi_keymap.c
	- `\' in vi insertion mode should be mapped to self-insert rather
	  than quoted-insert

				   10/27
				   -----
nojobs.c
	- added variable `already_making_children', made a function
	  start_pipeline called from make_child to set it, value cleared
	  in stop_pipeline.  This is how jobs.c treats it.

execute_cmd.c
	- in the `subshell' code in execute_command_internal, we need to
	  handle a possible `return' if in a function:
		f()
		{
			echo x | ( read b ; return 1 )
			return 0
		}
	  and treat it like an `exit'
	- already_making_children is no longer a job-control only variable
	- made the code that decides whether or not to wait for a child
	  process in the simple_command case of execute_command_internal
	  be the same for job control and non-job control shells, since
	  already_making_children has been put into nojobs.c

lib/readline/display.c
	- changed the display code to handle invisible characters in the
	  prompt and still wrap lines at the correct column.  wrap_offset
	  is the variable used to keep track of the number of invisible
	  characters in the buffer
	- changed rl_redisplay to use `screenchars' from readline.c so we
	  don't have to compute (screenwidth * screenheight) on each
	  redisplay

lib/readline/readline.c
	- new variable `screenchars', set to the total number of characters
	  on the screen we can use (screenwidth * screenheight)
	- changed rl_refresh_line so that it computes the line that the
	  cursor is on correctly, taking invisible characters into account

				   10/28
				   -----
general.h
	- changed declaration of vfree to xfree

general.c
	- renamed vfree to xfree, since some systems already have a vfree()
	  in libc

execute_cmd.c, jobs.c, builtins/read.def, builtins/common.c
	- changed vfree to xfree

shell.c
	- for systems that don't define USG and define ENOTSOCK, try to
	  use getpeername() in issock() to find out whether or not an
	  fd is a socket

documentation/bash.1, documentation/features.texi
	- documented the new \[ and \] prompt string escape sequences

documentation/bash.1, lib/readline/doc/rluser.texinfo
	- documented the new `show-all-if-ambiguous' readline variable

lib/readline/complete.c
	- changed rl_complete to call rl_complete_internal with `!' if
	  the variable `_rl_complete_show_all' is non-zero
	- changed rl_complete_internal to show all matches if there is
	  more than one and what_to_do is `!'

lib/readline/bind.c
	- new variable `show-all-if-ambiguous' to control the value of
	  _rl_complete_show_all
	- changed a call to alloca() in rl_parse_and_bind to a
	  malloc/free pair (`seq' variable), since some systems do not
	  allow alloca'd memory to be passed to a function
	- did the same alloca -> xmalloc/free in rl_generic_bind
	  (`keys' variable)

				   10/29
			           -----
dispose_cmd.h, make_cmd.h, command.h
	- added prototypes for the extern function declarations

variables.c
	- BSD/386 needs getenv to have a `const char *' argument

make_cmd.c
	- changed make_until_or_while to a static function

command.h
	- removed extern declarations for functions in make_cmd.c; those
	  are in make_cmd.h

				   11/1
				   ----
input.c
	- make sure that sync_buffered_stream returns a value

test.c
	- make sure that binary_operator returns a value

				   11/2
				   ----
cpp-Makefile
	- added a definition of GCC_LINT_FLAGS and GCC_LINT_CFLAGS to
	  generate lint-like warnings from gcc

siglist.h
	- cast references to sys_siglist[] in the `strsignal' macro
	  for the benefit of Linux

jobs.c, nojobs.c
	- changed all absolute references to sys_siglist to call the
	  strsignal macro instead

lib/readline/{readline.c,display.c,signals.c}
	- _rl_output_character_function is an int

lib/readline/rltty.c
	- outchar should return an int

general.c
	- use %ld to printf longs

builtins/trap.def
	- reordered code and eliminated some brace groups

builtins/ulimit.def
	- open_files() should return a long

shell.h
	- include <varargs.h> if HAVE_VARARGS_H is defined, not simply if
	  HAVE_VFPRINTF is defined

parse.y, execute_cmd.c, subst.c, trap.c, jobs.c
	- make sure that all function parameters are declared explicitly
	  and not defaulted to int

builtins/fg_bg.def
	- fixed a bug where last_asynchronous_pid could be set to a random
	  value if an unknown job or a non-job-control job was selected

test.c
	- added a missing `%s' to a call to test_syntax_error

cpp-Makefile
	- renamed `endian.h' to `bash-endian.h'; it seems that linux and
	  gnu libc use it in /usr/include.  What a pain in the ass.

				   11/4
				   ----
machines.h
	- add `#define HAVE_VARARGS_H' to the Linux machine description;
	  the auto-configuration process is unable to find it in the gcc
	  private include directories

				   11/5
				   ----
cpp-Makefile
	- COMPRESS_EXT should be `.gz'

general.h
	- have the BCOPY define for USG machines use `memmove' rather than
	  `memcpy', since that handles overlapping objects correctly

lib/readline/display.c
	- fixed the line updating code that checked whether a new line was
	  shorter or had fewer invisible characters that the visible line,
	  and called clear_to_eol with the right value and only in the
	  right cases

machines.h
	- added separate machine descriptions for NetBSD and FreeBSD

builtins/command.def
	- don't try to call confstr() on NetBSD

				   11/6
				   ----
machines.h
	- define HAVE_BCOPY for sgi
	- define HAVE_GETHOSTNAME for Linux and HPUX machines later than
	  hpux 6.2

general.h
	- remove the `if defined (sgi) from the clause that defines BCOPY

general.c
	- use new HAVE_BCOPY and HAVE_GETHOSTNAME defines instead of the
	  OS-specific symbols used before

				   11/8
				   ----
machines.h
	- for i386 machines running aix/ps2, use USE_TERMCAP_EMULATION,
	  since the terminfo database is more up-to-date than termcap

lib/readline/complete.c
	- make sure that X_OK is defined for the VISIBLE_STATS code

config.h, builtins/echo.def
	- added a DEFAULT_ECHO_TO_USG option for the echo builtin

lib/readline/rldefs.h
	- Xenix 2.2 systems, while mostly USGr3, do not have `sighold'
	  and related functions

lib/readline/isearch.c
	- added a variable `prev_line_found' to keep the incremental
	  searches from finding the same line two or more times in a
	  row

support/getcppsyms.c
	- recognize `_M_XENIX' and `mc68k32' symbols from cpp

tests/run-dollar-at-star-test
	- use `../bash' to point at the bash executable rather than
	  `../../sun4/bash'

general.h
	- some systems have a `strerror' define, so we need to protect
	  the extern function declaration

trap.h
	- use SIG_DFL rather than NSIG as the test of whether or not to
	  include <signal.h>, since Posix.1 does not require NSIG

				   11/9
				   ----
subst.c
	- new function get_word_from_string to slice a field off the front
	  of a string and skip trailing separators according to $IFS

builtins/read.def
	- changed read_builtin to use get_word_from_string to `incrementally'
	  do word splitting on the line read so that if fewer variable names
	  are given than words read, the separators in the original line are
	  preserved.  This makes `read' Posix.2 compliant.

				   11/10
				   -----
cpp-Makefile
	- add a sentinel file `parser-built' for y.tab.c and y.tab.h to
	  depend on, since there's no rule for telling make how to build
	  y.tab.h

shell.c
	- removed the #ifdef AUX code that sets up a 4.2 compatible
	  environment in favor of using the -ZP option to cc to create
	  a Posix executable (AUX 3.0)

jobs.c
	- changed sigwinch_sighandler so that it saves the window size
	  struct with the new values in shell_tty_info.c_winsize on AIX PS/2
	  Since readline calls the old sigwinch handler, this code should
	  be called no matter when the signal is received

support/mksysdefs
	- add code to define AIX_13 on AIX PS/2 version 1.3 machines

machines.h
	- there are different SYSDEP_CFLAGS and REQUIRED_LIBRARIES for
	  AIX PS/2 1.2 and 1.3, so use the AIX_13 define to differentiate

				   11/11
				   -----
execute_cmd.c
	- speedups and fixes for here document processing in
	  do_redirection_internal: don't do string processing we can
	  avoid, use stdio to help with write buffering if we're
	  expanding the document, close some file descriptor leaks

make_cmd.c
	- speed up gathering here documents: avoid expensive calls to
	  strncmp when possible, avoid a stupid strcpy when stripping
	  leading tabs, use BCOPY instead of strcpy

print_cmd.c
	- made varargs and non-varargs versions of cprintf() as similar
	  as possible
	- redid the_printed_command_resize() to be a little smarter about
	  allocating memory

subst.c
	- sped up string_list_internal by allocating all the necessary
	  space before copying rather than using xrealloc, using BCOPY
	  and an `end ptr' instead of strcat, trying not to call strlen
	  to get the separator length
	- sped up sub_append_string by using BCOPY instead of strcat,
	  being smarter about memory allocation, and cutting down calls
	  to strcpy
	- sped up expand_string_internal by not calling the
	  make_word/dispose_word pair, but by filling in a local
	  WORD_DESC, short-circuiting if the string is null or empty
	- don't bother trying to split words in expand_string_leave_quoted
	  if expand_string_internal returns a null list
	- ditto for dequoting in expand_string_unsplit

lib/readline/vi_mode.c
	- removed `w' and `W' from the list of characters that do not
	  require the point to be moved after a call to rl_vi_domove
	  in rl_vi_delete_to (`d') and rl_vi_yank_to (`y').  Only the
	  `c' command (rl_vi_change_to) requires this behavior

				   11/12
				   -----
subst.c
	- make sure all places which call expand_word_internal are
	  prepared to deal with error returns (expand_word_error
	  and expand_word_fatal) by adding a convenience function
	  call_expand_word_internal that performs the call and deals
	  with the possible error returns.  This keeps the shell
	  from dumping core on some errors

lib/readline/vi_mode.c
	- make sure <sys/types.h> is included before rldefs.h

parse.y
	- changed read_a_line to use and re-use a static line buffer

make_cmd.c
	- no longer need to free full_line, since read_a_line (called
	  from read_secondary_line), does not allocate a new one on
	  each call

builtins/psize.c, alias.c
	- need to include command.h before general.h

				   11/15
				   -----
documentation/features.texi, lib/readline/doc/{hsuser,rluser}.texi
	- fixed some spelling errors and typos

endian.c
	- include <sys/types.h> for size_t

Makefile.inc
	- new file, included in cpp-Makefile, providing biolerplate Gnu
	  make definitions

cpp-Makefile
	- include Makefile.inc
	- added `distclean', `realclean' targets as per Gnu coding
	  standards

				   11/17
				   -----
cpp-Makefile
	- `make install' now installs the documentation in $(mandir) and
	  $(infodir)
	- `make documentation' now passes $(MFLAGS) to the sub-make

documentation/Makefile
	- now has an `install' target

config.h
	- RESTRICTED_SHELL is no longer automatically defined

support/mksysdefs
	- Intel paragons (uname -m = paragon) need MAKE_ANSI set to true

lib/readline/history.c
	- create the history file with mode 0600, since it's supposed to
	  be private information

builtins/fc.def
	- make sure we put in the tab and `*' only if the line is actually
	  being listed to stdout rather than to a file for reexecution

				   11/17
				   -----
machines.h
	- fixed a typo in the hpux machine description
	- added some SYSDEP_CFLAGS to the __BSD_4_4__ description

README
	- corrected mail address for bash-maintainers

jobs.h
	- don't declare fork (), getpid (), and getpgrp () on __BSD_4_4__

				   11/18
				   -----
subst.c
	- fix to string_list_internal to make it return a null string if
	  handed a null list

parse.y
	- fix to find_reserved_word: `word' is declared as the argument, but
	  `token' is what's used in the body

lib/malloc/alloca.c
	- Crays need to define _getb67() as CRAY_STACKSEG_END

machines.h
	- ISC machines should be using USE_TERMCAP_EMULATION

				   11/19
				   -----
lib/readline/Makefile, lib/tilde/Makefile, lib/glob/Makefile, cpp-Makefile
	- change instances of `make' in recipes to `$(MAKE) $(MFLAGS)'

machines.h
	- SunOS4 needs `OPENDIR_NOT_ROBUST'
	- recognize a Motorola M88100 if m88k and USGr4 are defined, since
	  support/mksysdefs sets SYSDEF to USGr4 rather than M88100 for
	  the Motorola V.4
	- changes to the ISC entry to handle ISC version 4 as well as
	  version 3 using cc and gcc to compile

shell.c
	- fixed a typo (__POSIX_VERSION -> _POSIX_VERSION)
	- fixed a problem with reset_terminating_signals which caused the
	  wrong signal numbers to be checked for being trapped or
	  handled specially

lib/readline/vi_keymap.c
	- ^H in movement mode should by default be mapped to rl_backward
	- delete (^?) should be unbound in the default movement mode keymap

lib/readline/vi_mode.c
	- rl_vi_last_arg should insert a space before inserting the last
	  argument, according to Posix.2

getcwd.c
	- correctly declare the second argument as a size_t if __STDC__
	  is defined

				   11/20
				   -----
builtins/fc.def
	- go back to the ad-hoc option parsing style, because the builtin
	  getopt does not handle things like `fc -l -10' correctly

support/mksysdefs
	- fixed a typo problem defining $UnicosMachine that left a comment
	  unclosed

lib/malloc/alloca.c
	- bug fix from Bill Jones for CRAY_STACKSEG_END define

config.h, execute_cmd.c
	- fix for CRAY and defining `word'

machines.h
	- Crays need to define OPENDIR_NOT_ROBUST

bashtypes.h
	- sys/types.h with handling for multiple inclusion and Cray
	  peculiarities

execute_cmd.c, make_cmd.c, parse.y, subst.c
	- include `bashtypes.h' rather than <sys/types.h>

				   11/22
				   -----
machines.h
	- add definitions of CRAY_STACKSEG_END for Cray XMP and YMP
	- removed OLD_CRAY_DESCRIPTION stuff

lib/readline/rldefs.h
	- encapsulate CRAY peculiarities with casting pointers to ints
	  inside two defines: FUNCTION_TO_KEYMAP and KEYMAP_TO_FUNCTION

lib/readline/bind.c, lib/readline/readline.c
	- change code to use FUNCTION_TO_KEYMAP and KEYMAP_TO_FUNCTION

maxpath.h
	- include <sys/param.h> on the convex, but not on bsdi

newversion.c
	- overhauled and cleaned up
	- added the `-patch' argument to set the patch level of the shell
	- look in `.patchlevel' for the patch level and write it out as
	  PATCHLEVEL

version.c
	- new variable patch_level

shell.c
	- the version string is now `dist.patch(build)'
	- new function shell_version_string returns a pointer to the
	  version string, show_shell_version changed to use it

variables.c
	- bind $BASH_VERSION to the value of shell_version_string ()

				   11/23
				   -----
machines.h
	- SCO machines now include -DPGRP_PIPE in the SYSDEP_CFLAGS define
	- HPUX_9 needs an #undef HAVE_RESOURCE; it appears that they've
	  finally removed getrusage

trap.c
	- signal_name should return an error when passed NSIG

parse.y
	- add AND_AND and OR_OR to the list of tokens which are not followed
	  by a semicolon
	- decrement current_command_line_count if pre_process_line returns
	  a null or empty string, otherwise the next input line may be
	  combined with the previous line inappropriately

				   11/24
				   -----
machines.h
	- the KSR/1 section should be delimited by `__ksr1__', added some
	  SYSDEP_CFLAGS to that description

support/mksysdefs
	- quote all the arguments to expr

support/getcppsyms.c
	- recognize and pass on `__ksr1__'

lib/readline/bind.c
	- new inputrc variable `output-meta', which means output meta
	  chars without converting them to M- sequences

lib/readline/readline.c
	- new variable `_rl_output_meta_chars' to hold value of
	  `output-meta', initially off
	- slight efficiency improvement to rl_insert_text, rl_forward,
	  rl_backward
	- changed the order of args to rl_kill_text in rl_unix_word_rubout
	  so that multiple words can be killed and yanked out in the
	  `right' order

lib/readline/display.c
	- changes to use the value of `_rl_output_meta_chars' to decide how
	  to output characters with the eighth bit set

documentation/bash.1, lib/readline/doc/rluser.texinfo
	- documented new readline `output-meta' variable

lib/readline/complete.c
	- make the replacement of typed text by a completion match be a
	  single undoable event

builtins/type.def
	- call user_command_matches specifying FS_EXEC_ONLY as the search
	  criteria.  This keeps test from finding directories

bashhist.c
	- changed maybe_save_shell_history so that if the history has
	  been stifled then the history file is replaced with the current
	  history list

				   11/29
				   -----
builtins/exec.def
	- if the shell is restricted, exec is not allowed

cpp-Makefile
	- more changes for GNU standards: VPATH, libdir, srcdir

jobs.h
	- remove machine-specific undefining of HAVE_WAIT_H

machines.h
	- cadmus systems need to #undef HAVE_WAIT_H
	- hpux_usg and hpux_6 systems need to #undef HAVE_WAIT_H
	- added a section for `Irix5' to the sgi section

documentation/Makefile
	- fixed up the install for bash_builtins.1 so that it sets the .so
	  path correctly

shell.c
	- renamed issock to isnetconn and made its inclusion unconditional
	- added a check for S_ISCHR for SVR4 and SVR4.2 systems to isnetconn

subst.c
	- added code so that `history_control=ignoreboth' works

documentation/bash.1, documentation/features.texi
	- added a description of `ignoreboth' to the text describing
	  `history_control'

				   11/30
				   -----
input.c
	- don't print an error message in check_bash_input if the fnctl
	  to dup the file descriptor fails unless the file descriptor
	  is already active

jobs.c, nojobs.c
	- set bash_input.location.buffered_fd to -1 when setting
	  default_buffered_input to -1 in make_child.  This fixes
	  the `( echo hi 1>&3 ) 3>&1 >/dev/null' spurious error message

shell.c, error.c
	- removed the automated bug report code

support/bashbug.c
	- is no more

Makefile
	- added GNU boilerplate definitions

support/bashbug.sh, support/mkbashbug
	- new files for a BSD sendbug-like bug reporting shell script

cpp-Makefile
	- changes to use $(SUPPORT_SRC) instead of $(SDIR) under some
	  circumstances
	- removed references to support/bashbug.c
	- new target to make bashbug from $(SUPPORT_SRC)/bashbug.sh using
	  $(SUPPORT_SRC)/mkbashbug
	- bashbug is now created by default
	- don't build endian.aux or create bash-endian.h if HAVE_WAIT_H
	  is defined, because it will end up being unused anyway

machines.h
	- add OPENDIR_NOT_ROBUST to the isc386 description

signames.c
	- make the signal_names array 2 * NSIG long to hack around HP/UX
	  misfeature

builtins/test.def
	- fixed the help text for -t to note the the fd argument is not
	  optional

				   12/1
				   ----
builtins/common.c
	- changed parse_and_execute so that it no longer unconditionally
	  sets `interactive' to 0.  It is now the responsibility of callers
	  of parse_and_execute to set it how they want, and reset it if
	  necessary

shell.c, subst.c, builtins/source.def
	- changed the functions that call parse_and_execute to manage the
	  value of `interactive'

shell.c
	- changed maybe_execute_file so that it takes a second argument
	  saying whether or not to force the value of `interactive' to 0
	- changed all calls to maybe_execute_file to add a second arg

builtins/fc.def, builtins/exit.def
	- changed all calls to maybe_execute_file to add the second arg
	  Now background jobs re-run with `fc -s' echo the job number

externs.h
	- changed the function prototype for maybe_execute_file

				   12/2
				   ----
execute_cmd.c
	- rewrote the auto-resume code in execute_simple_command for clarity
	- added the `substring' value for auto_resume to cause a command that
	  matches a substring of a stopped job to restart that job

documentation/bash.1, documentation/features.texi
	- added a description of the possible values for `auto_resume' and
	  their effects on the shell's behavior

machines.h
	- added a generic desription for SVR4 running on the sparc from
	  Ian Stewartson

Makefile
	- added a command to the bash-Makefile target that will remove
	  bash-Makefile and (hopefully) stop the make if something happens
	  and bash-Makefile is created with zero length

				   12/3
				   ----
machines.h
	- add -DOPENDIR_NOT_ROBUST to the SYSDEP_CFLAGS for SCO
	- if compiling with gcc on SCO, link with -lc_s and -lc in
	  REQUIRED_LIBRARIES

				   12/6
				   ----
builtins/source.def
	- new variable `sourcelevel' which is incremented each time `.'
	  is called and decremented before source_builtin returns

variables.c
	- find_variable should call find_variable with a second parameter
	  of 1 if `builtin_env' is non-null, so it will search it.  This
	  ensures that all builtins inside a script read with `.' with a
	  temporary environment will get the right values

subst.c
	- fix for get_word_from_string: white space should be removed from
	  the beginning of the string if $IFS is " \t\n"

execute_cmd.c
	- in `Posix.2 mode', redirections should not perform filename
	  expansion when the shell is not interactive

				   12/7
				   ----
support/getcppsyms.c
	- recognize `__i386__'

lib/readline/bind.c
	- only free and reassign `last_readline_init_file' if it has
	  changed (`filename' points to something different) in
	  rl_read_init_file

builtins/ulimit.def
	- add a `$DEPENDS_ON !MINIX' line so that this won't be built
	  under MINIX

config.h
	- Minix machines need JOB_CONTROL undefined

cpp-Makefile
	- don't define libraries with absolute pathnames; use -llibname
	  instead
	- make sure MALLOC_LIBRARY is defined even if the Gnu malloc is
	  not being used for the benefit of `LD_HAS_NO_DASH_L'

general.c
	- use a `TIMEVAL_MISSING' define to decide whether or not to
	  try to print a struct timeval * rather than simply `USG'

lib/readline/parens.c
	- don't try to include <sys/time.h> unless FD_SET is defined

lib/readline/vi_keymap.c
	- fix incorrect cast of rl_abort in vi_movement_keymap

signames.c
	- make sure NSIG is defined

siglist.c
	- include `trap.h' to pick up definition of NSIG if it's undefined

siglist.h
	- minix uses _sys_siglist and does not need an external declaration
	  for it

				   12/8
				   ----
lib/readline/readline.c
	- add `ks' and `ke' to the termcap attributes that readline retrieves

lib/readline/rltty.c
	- new function `control_keypad' to enable and disable keypad keys.
	  Some systems need this before the arrow keys will work
	- call control_keypad to enable and disable the keypad from the
	  terminal prep and deprep code

				   12/9
				   ----
support/mksysdefs
	- added code a la trn `Configure' to search a list of include
	  directories for each .h file of interest.  Done by defining a
	  variable containing the code fragement we want to execute and
	  calling `eval' on this string for each file

lib/readline/bind.c
	- slightly changed the filenames used by rl_read_init_file.  Now
	  the filename used is the first non-null file from this list:
		1. the filename used for the previous call
		2. the value of the shell variable `INPUTRC'
		3. ~/.inputrc

documentation/bash.1
	- added descriptions of INPUTRC to the shell variables and
	  readline sections

documentation/features.texi
	- added a description of INPUTRC to the shell variables section

lib/readline/doc/rluser.texi
	- added description of the INPUTRC environment variable
	- changed instances of ~/.inputrc to the more generic `init file'
	  or `inputrc file'

lib/readline/complete.c
	- added #defines for the possible values of `do_replace' rather
	  than relying on magic numbers
	- if a completion that needs double quotes starts with a tilde,
	  rl_complete_internal now performs tilde expansion before
	  quoting the string, since the shell allows double quotes to
	  inhibit tilde expansion

				   12/10
				   -----
lib/readline/readline.c
	- new function to kill the whole line no matter what point is:
	  rl_kill_full_line ()

lib/readline/readline.h
	- extern declaration for rl_kill_full_line ()

lib/readline/funmap.c
	- rl_kill_full_line is available as `kill-entire-line'

cpp-Makefile
	- remove `.machine' when `make clean' run

subst.c, subst.h
	- made expand_string_leave_quoted static again

				   12/14
				   -----
shell.c
	- use HAVE_SOCKETS define to decide whether to include <sys/socket.h>
	  and call getsockname(); defined automatically for non-USG systems
	  if ENOTSOCK is defined

				   12/15
				   -----
bashline.c, flags.c, flags.h, jobs.c, subst.c, builtins/common.c,
builtins/cd.def

	- made `set -?' print a usage message

subst.c
	- made sv_nolinks set the new variable `no_symbolic_links'

				   12/17
				   -----
machines.h
	- add -DUSG to HPUX_CFLAGS
	- hpux 9 does not need -lPW and can use the gnu malloc if gcc
	  is being used

config.h
	- remove the code that defines USG for HPUX, Xenix, and UNIXPC
	  in favor of putting it into the machines.h entry

				   12/19
				   -----
flags.h
	- added prototypes for the extern function declarations from flags.c

*.h
	- added copyrights to the include files which were missing them

lib/readline/vi_mode.c
	- rl_vi_yank_nth arg inserted the space in the wrong spot before
	  yanking the last argument
	- removed the call to rl_vi_insertion_mode because of changes to
	  rl_yank_nth_arg

lib/readline/readline.c
	- changed rl_yank_nth_arg so that vi mode inserts a space in the
	  right spot
	- fixed rl_yank_nth_arg so that yanking into an empty line does
	  not corrupt the buffer

lib/readline/search.c
	- fixed noninc_search so that ^H and RUBOUT call rl_rubout
	  explicitly

bashline.c
	- fix for operate_and_get_next to make ^O work on the most
	  recent line even if the history is unstifled.  From Seth
	  Robertson.  XXX - may not be right

parse.y
	- set interactive to 0 before calling parse_and_execute in
	  execute_prompt_command to stop infinite recursion through
	  this function

shell.c
	- moved the code that executes PROMPT_COMMAND to parse_command

parse.y
	- removed the code that executes PROMPT_COMMAND from read_token
	  to avoid confusing non-reentrant versions of yacc
	- made execute_prompt_command global, not static

input.h
	- new declaration for execute_prompt_command 

jobs.c
	- made give_terminal_to return -1 if tcsetpgrp fails
	- initialize_jobs now prints a message if job_control ends up being
	  set to 0

support/mkmachtype
	- shell script stolen from emacs 19 that attempts to output the
	  `GNU-style' machine type, e.g. sparc-sun-sunos4.1.2.  Named
	  `mkmachtype' because I envision people assigning its output to
	  a MACHTYPE variable


				   12/20
				   -----
execute_cmd.c
	- if a command is found in the temporary $PATH, don't add it to
	  the hash table

error.c
	- changed report_error so that the script name is echoed instead
	  of the shell name if the shell is not interactive

				   12/22
				   -----
machines.h
	- made the Sun description unconditionally #undef USE_GNU_MALLOC
	  because memory access bugs are legion in libc in SunOS 4.x and 5.x

jobs.c
	- disabled printing an error message when the tcgetattr in
	  get_tty_state() fails

				   12/27
				   -----
cpp-Makefile, jobs.h
	- renamed bash-endian.h to bash_endian.h

machines.h
	- NeXT machines need to #undef HAVE_DIRENT_H, since it requires
	  ANSI/POSIX defines that make the rest of the compilation fail
	- SGI irix 5.x machines need -DNO_SBRK_DECL in SYSDEP_CFLAGS
	- machine descriptions for OSF/1 running on i386 and MIPS machines
	  from Michael Meissner

				   12/28
				   -----
expr.c
	- fixed so that blank expressions evaluate to 0 rather than an
	  error ($[    ] or $((    )))

lib/readline/readline.c
	- new variable `_rl_bell_preference' replacing _rl_prefer_visible_bell
	- changed ding() to use _rl_bell_preference

lib/readline/rldefs.h
	- definitions for NO_BELL, AUDIBLE_BELL, and VISIBLE_BELL

lib/readline/bind.c
	- changed rl_variable_bind to parse the `bell-style' variable and its
	  possible values (`none', `audible', or `visible'), keeping
	  `prefer-visible-bell' for backwards compatibility

documentation/bash.1, lib/readline/doc/rluser.texinfo
	- added descriptions of the `bell-style' and `expand-tilde'
	  readline variables

general.c
	- changed set_signal_handler for posix systems to attempt to
	  restart all interrupted system calls execept for SIGALRM

trap.c
	- changed restore_signal to use set_signal_handler() instead of
	  signal()
	- added a new function set_signal_ignored to set the SIG_HARD_IGNORE
	  flag for a particular signal

execute_cmd.c
	- call set_signal_ignored for SIGINT and SIGQUIT in the child if
	  the command is asynchronous after calling restore_original_signals,
	  since restore_original_signals will undo work done by make_child
	  done in a new function setup_async_signals

execute_cmd.h
	- extern declaration for setup_async_signals

subst.c
	- call setup_async_signals when making the child for process
	  substitution

jobs.c, nojobs.c
	- removed code from make_child that sets SIGINT and SIGQUIT to
	  SIG_IGN, since setup_async_signals now does that

shell.c
	- let throw_to_top_level call longjmp with DISCARD if the shell
	  is an interactive shell, but not yet initialized

				   12/29
				   -----
config.h
	- define PROCESS_SUBSTITUTION if HAVE_DEV_FD is defined, even if
	  MKFIFO_MISSING is also defined

execute_cmd.c
	- close pipes created using /dev/fd for process substitution at
	  the same time as the pipes for conventional piping are closed

subst.c
	- when the /dev/fd list is initialized, clamp the total number of
	  file descriptors at 256, but make sure there is room enough to
	  store a bit for the fd passed to add_fifo_list

				   12/30
				   -----
lib/readline/readline.c
	- change a strncpy() in rl_delete_text to a for loop, since some
	  versions of strncpy can't handle overlapping arguments

lib/readline/chardefs.h
	- definition for digit_value(x)

lib/readline/history.c
	- changed calls to sscanf followed by an empty for loop that consumes
	  the digits to a for loop that computes the value as it goes along
	  in get_history_word_specifier()
	- added `x*' and `x-' history word designators from csh
	- added new `&' modifier to repeat previous substitution
	- experimental implementation of `q' modifier to quote substituted
	  words by calling single_quote on the substituted string

lib/readline/history.c, builtins/fc.def
	- changed a loop using strncmp() to find one string in another for
	  substitution to test the current character against the first
	  character of the pattern before calling strncmp()

documentation/bash.1, lib/readline/doc/hsuser.texinfo
	- documented the new history word designators
	- documented new `&' and `q' history modifiers

				    1/1
				    ---
parse.y
	- broke the code that parses `( ... )' subshells out into its
	  own grammar production

lib/readline/history.c
	- rearranged some code to get rid of gotos and make the intent
	  clearer
	- fixed a bug in history_truncate_file that tried to write to
	  a file opened O_RDONLY
	- changed a stat-open in history_truncate_file into an open-fstat
	  pair
	- removed gotos in history_search_internal
	- changed straight strncmp() calls trying to find history line
	  matches to check the first character before calling strncmp in
	  history_search_internal
	- changed a call to stat after an open (!) to fstat on the
	  returned file descriptor
	- cleaned up the code in get_history_event
	- cleaned up some code in get_history_word_specifier
	- cleaned up some code and removed extra function calls in
	  history_arg_extract
	- changed history_arg_extract to malloc enough space for the
	  entire string at one time, instead of doing xrealloc in a
	  loop
	- cleaned up the code in history_tokenize, removing gotos and
	  other spaghetti constructs
	- replaced a call to sprintf with assignment statements and a call
	  to strcpy in history_expand

cpp-Makefile
	- changed the `INDEX' target to a `TAGS' target

lib/readline/emacs_keymap.c
	- added a default binding for ESC-ESC to rl_complete, like ksh emacs
	  mode editing

				    1/3
				    ---
machines.h
	- make sure ISC_POSIX is defined as nothing when using gcc on isc386

parse.y
	- made token_to_read, current_token, last_read_token,
	  token_before_that, EOF_reached, shell_input_line,
	  shell_input_line_*, token, token_buffer_size all static vars
	- made prompt_again return immediately if the shell is not
	  currently interactive
	- made yylex call prompt_again only if there is no token_to_read
	  and the shell is currently interactive

jobs.c
	- changed the NeXT || alliant define to use RLOGIN_PGRP_BUG
	- use TERMIOS_LDISC define for systems with line discipline field
	  in struct termios

shell.c
	- use RLOGIN_PGRP_BUG instead of NeXT to fix machines that get
	  started without a controlling terminal

machines.h
	- added -DRLOGIN_PGRP_BUG to SYSDEP_CFLAGS for NeXT and alliant
	- added -DTERMIOS_LDISC to SYSDEP_CFLAGS for Ultrix, Sun OS 4,
	  and aixpc

support/mksysdefs
	- look for sys/param.h, define HAVE_SYS_PARAM if found

cpp-Makefile
	- pass -DHAVE_SYS_PARAM via SYSTEM_FLAGS if it's found by mksysdefs

maxpath.h
	- include <sys/param.h> if HAVE_SYS_PARAM is defined

lib/readline/history.c
	- got rid of the get_which label in get_history_event
	- got rid of the event_not_found label in history_expand
	- new function hist_error, which takes care of printing history
	  expansion errors

				    1/4
				    ---
lib/readline/history.c
	- split the actual history expansion code out of history_expand into
	  history_expand_internal
	- got rid of the do_add and add_char labels in history_expand
	- history_expand now returns 2 if the `p' modifier was given and the
	  caller should just print the results
	- new function `quote_breaks' to implement the `x' modifier

bashhist.c
	- if history expansion fails, make sure the error message is
	  printed in a standard way by calling internal_error
	- print the results of history_expand and return NULL if
	  history_expand returns 2

				    1/5
				    ---
lib/readline/history.c
	- rearranged some code in the `s' and `&' cases of the switch in
	  history_expand_internal, added the GET_SUBST_PATTERN macro

				    1/6
				    ---

	- made process substitution work only when unquoted

bashhist.c
	- new function history_number to return the history number of a
	  command

bashhist.h
	- extern declaration for history_number

parse.y
	- changed the `!' and `\!' code in decode_prompt_string to use
	  history_number
	- replaced calls to sprintf/savestring with calls to itos()

variables.c
	- new dynamic variable $HISTCMD is current history number (what
	  you get with \! in a prompt string)

documentation/bash.1
	- description of $HISTCMD

				    1/7
				    ---

execute_cmd.c
	- new variable stdin_redir, incremented for subshells if stdin has
	  been redirected, saved for children so we don't redirect /dev/null
	  to fd 0 if it has already been the subject of a redirection.  Makes
	  bash more sh-compatible, but I'm not sure it's the right thing.
	- more changes to file_status for systems with AFS

test.c
	- changed calls to eaccess to EACCESS (not to be confused with the
	  EACCES error).  EACCESS is defined as access on AFS machines,
	  eaccess on all others

siglist.h
	- don't declare sys_siglist on NetBSD

				   1/11
				   ----
lib/readline/history.c
	- if `&' appears in the rhs of a history substitution, it is
	  replaced with the matched lhs.  A single backslash protects
	  the `&' from lhs interpolation
	- fixed ADD_CHAR macro to properly terminate the target string
	- changed GET_SUBST_PATTERN so that a single backslash can
	  quote the substitution delimiter
	- changed GET_SUBST_PATTERN so that subst_lhs is not changed if
	  the lhs pattern is empty
	- if the lhs is empty and there is no previous substitution, the
	  last string used in a !?string? search is used
	- turned the GET_SUBST_PATTERN macro into a real function,
	  get_subst_pattern()
	- changed get_subst_pattern() so that backslashes quoting the
	  search delimiter are removed
	- fixed get_history_word_specifier so that x- returns x-$ without
	  the last word

documentation/bash.1, lib/readline/doc/hsuser.texinfo
	- changes for the new history substitution features

				   1/13
				   ----
make_cmd.c
	- new function fixup_async_list() which traverses a command list and
	  makes the last command asynchronous (`&').  This is to fix up a
	  problem with the yacc grammar productions

parse.y
	- call fixup_async_list if a list is followed by a bare `&' without
	  a second list

builtins/fc.def
	- fixed a bug in fc_gethnum that caused negative history
	  specifications (< 0) to be off by 1 when indexing against the
	  current history index

lib/readline/funmap.c
	- kill-entire-line -> kill-whole-line
	- tilde-expand is now a bindable command that calls rl_tilde_expand
	- added emacs-editing-mode as a bindable command

	- added documentation for some of the new readline functions

test.c
	- added definitions for whitespace, digit, and digit_value when
	  compiling -DSTANDALONE

				   1/14
				   ----
make_cmd.c, make_cmd.h, parse.y
	- fixup_async_list -> connect_async_list

parse.y
	- have the productions for all async lists call connect_async_list,
	  even when followed by another async list
	- don't save and restore the buffered stream in buffers[] in
	  push_stream and pop_stream if the default input fd is -1
	  (like command substitution sets it to, for instance)

cpp-Makefile
	- added $(PURIFY) the final cc line, make PURIFY=purify to build
	  a `purified' bash

builtins/read.def
	- fixed a memory leak -- `input_string' was not being freed

variables.c
	- fixed a memory leak in assign_in_env -- free value

subst.c
	- process substitution and command substitution now call make_child
	  with a null first argument -- no need to save a string for the
	  call; it's never used

				   1/17
				   ----
lib/readline/{readline.h,complete.c}
	- renamed rl_symbolic_link_hook to rl_directory_completion_hook,
	  which much more accurately reflects its purpose.  Left a define
	  of the old name there is readline.h

bashline.c
	- use rl_directory_completion_hook instead of rl_symbolic_link_hook
	- bash_symbolic_link_hook -> bash_directory_completion_hook
	- bash_directory_completion_hook is now an `int' returning function
	- bash_directory_completion_hook now tries to to variable expansion
	  and command and arithmetic substitution if the directory name
	  contains `$' or ``'
	- fixed a bug in bash_directory_completion_hook which made it
	  remove the trailing slash on a directory name
	- bash_directory_completion returns 1 if variable expansion is
	  performed, 0 otherwise
	- when doing bash filename-specific completion, don't do any kind
	  of directory name expansion
	- removed ``' and `$' from the completer word break characters;
	  they're not word break chars

lib/readline/complete.c
	- changed semantics for rl_directory_completion_hook -- if a non-zero
	  value is returned, the return value is put into the expanded
	  filename, replacing the directory name that the user typed
	- changed filename_completion_function to quote a replacement if
	  it contains `$' or ``' in addition to characters appearing in
	  rl_completer_word_break_characters (#ifdef SHELL)

				   1/18
				   ----
shell.c
	- take out different code for USG and BSD and mail checking.  The
	  shell always calls remember_mail_dates on startup.

				   1/19
				   ----
execute_cmd.c
	- changed executable_file into a simple return statement

support/mksysdefs
	- look for bison, define HAVE_BISON if found

				   ----
machines.h
	- added -DNO_SBRK_DECL to hpux_8, hpux_9, and Solaris descriptions

machines.h
	- define HAVE_SOCKETS in HPUX_SYSDEP_CFLAGS for hpux_8 and hpux_9

Makefile
	- add a `tests' target that just runs `make -f bash-Makefile tests'

general.c
	- include config.h before any other include files so <unistd.h>
	  gets included if present

				   1/24
				   ----
cpp-Makefile
	- make `bashbug' by using sed with multiple -e options rather than
	  a separate `mkbashbug' program

				   1/25
				   ----
machines.h
	- sgi machines need HAVE_SOCKETS defined to make isnetconn() work

lib/readline/isearch.c
	- rewrote lots of rl_search_history to eliminate spaghetti and
	  increase speed

lib/readline/history.c
	- added defines for STREQ and STREQN to clean up the search code

lib/readline/complete.c
	- compare the first characters of the name and returned value from
	  getpwent when attempting username completion to avoid all those
	  calls to strncmp

				   1/26
				   ----
lib/readline/readline.h
	- move definition of VISIBLE_STATS here so all files can see it
	- extern definitions of rl_history_search_forward() and
	  rl_history_search_backward ()

lib/readline/search.c
	- implementations of rl_history_search_forward() and
	  rl_history_search_backward (), which search through the history
	  list for lines beginning with the string of characters between
	  the beginning of the line and rl_point (history lines with a
	  common prefix)
	- added definitions of STREQ and STREQN

lib/readline/funmap.c
	- added `history-search-forward' and `history-search-backward' as
	  bindable commands (names compatible with tcsh)

lib/readline/complete.c
	- make stat_char use lstat if S_ISLNK is defined to pick up symbolic
	  links
	- split some common code out into auxiliary functions: printable_part
	  and print_filename
	- expand filenames before calling stat_char if visible-stats is
	  active

documentation/bash.1, documentation/readline.3, lib/readline/doc/rluser.texinfo
	- documented new `history-search-forward' and `history-search-backward'
	  readline commands, by default unbound

error.c
	- changed get_name to get_name_for_error and made it externally
	  visible

error.h
	- extern declaration for get_name_for_error

test.c
	- call get_name_for_error in test_syntax_error if the shell is
	  not interactive

builtins/common.c
	- if parse_and_execute gets an interrupt during execution, make
	  sure that `interactive' is restored to the correct value (the
	  same value as `interactive_shell' before throwing control back
	  to the top level with throw_to_top_level so the shell does

	  the descriptions

				   2/18
				   ----

jobs.c, nojobs.c
	- changed some calls to report_error to calls to internal_error

	  into an internal function that takes a pointer to a function to
	  use to print the words

variables.c
	- don't call savestring in bind_variable on the value if it's an
	  empty string

nojobs.c
	- changed wait_for to call waitpid with -1 for pid value on Posix
	  systems so all processes in a pipeline get reaped at the same
	  time (or at least most of them)

				   2/21
				   ----
lib/readline/{complete.c,display.c,readline.c,rltty.c,signals.c}
	- changed _GO32_ to __GO32__

machines.h
	- SunOS5 needs to add /usr/ccs/lib to the library search path
	  for the right termcap library

				   2/22
				   ----
shell.c
	- make sure that a subshell sets sourced_env to 0 after longjmp
	  so that $ENV is sourced by subshells forked to execute scripts
	  without a leading `#!' line

bashhist.c, bashhist.h
	- make maybe_add_history a global interface -- new function
	  to add a line to the history file depending on the value
	  of history_control

builtins/fc.def
	- call maybe_add_history in fc_addhist rather than add_history

machines.h
	- new entry for concurrent machines in att universe from
	  geoffl@vallista.ca.boeing.com (Geoffrey A. Lowney)

				   2/23
				   ----
general.c, general.h
	- new function string_to_long, which basically does the same
	  thing as atol(), which I don't believe is universal

builtins/ulimit.def
	- replaced a call to sscanf with calls to all_digits and
	  string_to_long
	- non-root users can only raise a resource up to the hard limit,
	  even if they specify `unlimited', so shell_ulimit translates
	  RLIM_INFINITY into limit.rlim_max if euid != 0

				   2/25
				   ----
shell.c
	- make the default behavior of bash when invoked with -c command
	  to make the first argument after the command string $0 and the
	  rest $1...$N

documentation/bash.1
	- document the change in -c behavior

				    3/2
				    ---
mailcheck.c
	- made add_mail_file return the index in the list of mail files,
	  so an immediate call to find_mail_file need not be made and
	  we are guaranteed that the index returned is never -1
	- added the check back in that changes the message to note that
	  *new* mail has arrived -- the test was not redundant after all
	- fixed an off-by-one error in free_mail_files
	- replaced an sprintf() in get_mailpaths with two calls to strcpy

general.c
	- changed getc_with_restart to do local buffering to reduce the
	  number of read(2) system calls

subst.c
	- changed do_assignment_internal to check for expansion and quoting
	  characters and only call expand_string when something needs
	  expansion, string_quote_removal when quotes appear, and savestring
	  for simple assignment statements

				    3/3
				    ---
builtins/exit.def, documentation/bash.1
	- removed `bye' as a synonym for `exit'

shell.h
	- new exit value: EX_USAGE

builtins/{bind,command,declare,fc,getopts,histctl,history,inlib,jobs,read,
setattr,trap,ulimit}.def
	- changed to return EX_USAGE when a usage message is printed

	- code to execute select commands

make_cmd.c
	- code to construct select command structures

	  returned by read_token only if SELECT_COMMAND is defined

print_cmd.c
	- code to print select commands

config.h, config.h.mini
	- make SELECT_COMMAND the #define that controls whether or not the
	  `select' command is compiled in

documentation.bash,1, documentation/features.texi
	- documented the `select' command and $PS3

				    3/4
				    ---
builtins/getopts.def
	- removed a call to sprintf() in favor of expanding a number manually

builtins/getopt.c
	- make sure that we set nextchar to NULL when incrementing optind
	  so that it does not end up pointing to stale memory (freed, then
	  later reallocated)

				    3/7
				    ---
builtins/common.c
	- fixed parse_and_execute not to be overzealous in marking a command
	  as NO_FORK -- make sure there's nothing left in the string to be
	  executed before doing so

machines.h
	- change the string check for BSD/386 to __bsdi__
	- add INT_GROUPS_ARRAY to BSDI, SunOS4, 386bsd, FreeBSD, and NetBSD
	  descriptions

test.c
	- change to use INT_GROUPS_ARRAY

execute_cmd.c
	- tightened up the execution loop in execute_for_command and
	  removed a couple of unneeded variables

lib/posixheaders/memalloc.h
	- make sure to check for sun being defined when checking for sparc;
	  there are ICL DRS6000 machines running SVR4.2 out there that do
	  not have the file

				    3/8
				    ---
execute_cmd.c
	- make sure close_fd_bitmap is called before do_redirections, lest
	  the bitmap override some of the redirections

cpp-Makefile
	- supply an explicit suffix list, so make understands the .def.o
	  suffix rule as such

				    3/9
				    ---
jobs.h
	- added extern declarations for rest of global functions in jobs.c
	- added prototypes

jobs.c
	- made delete_job, terminate_current_pipeline, kill_current_pipeline,
	  describe_pid, notify_and_cleanup, reap_dead_jobs,
	  initialize_job_signals , without_job_control void functions

				   3/10
				   ----
execute_cmd.c, execute_cmd.h
	- moved check_identifier to general.c, general.h

general.c
	- check_identifier has acquired a second parameter; when set to 1
	  this causes the word to be checked by legal_identifier
	- for and select commands call check_identifier with a second arg
	  of 1, function names are checked with legal_identifier when in
	  Posix.2 mode

general.h
	- add second argument to extern declaration of check_identifier

CWRU/POSIX.NOTES
	- added description of new function name behavior

lib/readline/readline.h
	- include sys/ioctl.h on FreeBSD and NetBSD

lib/readline/rlconf.h
	- new file, with readline configuration variables
	- included in rldefs.h

lib/readline/{readline.c,readline.h,complete.c,display.c}
	- took configuration defines out and put them into rlconf.h

lib/readline/Makefile
	- updated dependencies to include rlconf.h

				   3/14
				   ----
lib/readline/Makefile
	- remove VI_MODE from the CFLAGS

lib/readline/rlconf.h
	- made VI_MODE a definable configuration option

lib/readline/vi_mode.c
	- include rlconf.h before testing whether or not VI_MODE is defined

lib/readline./funmap.c
	- include `rlconf.h' before `readline.h'

lib/readline/keymaps.c
	- include `rlconf.h' before `vi_keymap.c' and `keymaps.h'

lib/readline/readline.c, lib/readline/vi_mode.c
	- rl_vi_set_last -> _rl_vi_reset_last
	- new function _rl_vi_set_last to set the vi-mode last command
	  information
	- renamed vi_done_inserting to _rl_vi_done_inserting

lib/readline/vi_mode.c
	- _rl_vi_last_command, _rl_vi_last_repeat, _rl_vi_last_arg_sign,
	  and _rl_vi_doing_insert are now static

				   3/15
				   ----
bashline.c
	- unbind C-M-m in emacs_meta_keymap so people don't accidentally
	  switch into vi editing mode

				   3/21
				   ----
builtins/cd.def
	- `pwd' now follows the setting of nolinks/set -o physical; there
	  is an undocumented -P option to get the `real' working directory

				   3/28
				   ----
make_cmd.c
	- only follow the command chain to the end of a list in
	  connect_async_list if the list is not being executed in the
	  background as a unit with CMD_WANT_SUBSHELL

support/mksysdefs
	- removed the define of HAVE_CSH
	- added an additional check for SVR4 on i[34]86 machines from
	  mkmachtype

lib/readline/vi_mode.c
	- fix up rl_vi_delete_to so that cw deletes the character under
	  the cursor no matter what, as per Posix.2
	- any text modifying command that calls rl_vi_insertion_mode needs
	  to explicitly set the `last command' info for `.'
	- rl_vi_movement_mode() no longer resets the `last command' info
	  so that things like `cw' can be redone with `.'

				   3/29
				   ----
general.h
	- a new define MEMMOVE_MISSING to specify to use memcpy in the
	  define for BCOPY
	- the defines for BCOPY don't need a trailing `;'

machines.h
	- isc386 needs -DMEMMOVE_MISSING in SYSDEP_CFLAGS

				   3/30
				   ----
bashline.c

	- change the bug report message 

support/mksysdefs
	- removed `WHOAMI' junk for setting the `maintainer'

cpp-Makefile
	- hardcode the maintainer to `bug-bash@prep.ai.mit.edu'

subst.c
	- call rl_reset_terminal in sv_terminal if interactive_shell
	  is nonzero
	- split the code that checks whether or not expand_string_unsplit
	  needs to be called from do_assignment_internal into a separate
	  function that takes a function pointer to call as an additional
	  parameter

trap.c
	- make sure that set_signal_ignored also sets original_signals[sig]
	  to SIG_IGN

bashline.c
	- `{' is not a word break character for the completion functions

				    4/2
				    ---
[first beta distribution of bash-1.14.0]

				    4/5
				    ---
builtins/cd.def
	- fixed a problem with CDPATH processing (used `dirlen' instead of
	  `pathlen')

subst.c
	- make sure that get_word_from_string updates `stringp' even if
	  it's nothing but separators

builtins/read.def
	- after the call to get_word_from_string, set *e to 0 only if t
	  is not null and a word was actually returned

machines.h
	- remove the NO_SBRK_DECL declaration for sgi machines from all
	  but Irix 5.x machines
	- sgi needs __STDC__ defined if __EXTENSIONS__ is defined

lib/posixheaders/stdc.h
	- moved the #if defined (__P) inside the check for __STDC__, so
	  the other things get defined even if __P is already defined
	- don't redefine const, inline, etc. if `const' is already defined

cpp-Makefile
	- add dependencies on stdc.h
	- pass -DHAVE_SYS_STREAM_H through to builds in subdirs

support/mksysdefs
	- redirect error messages from subshell attempting to find and invoke

externs.h, print_cmd.c
	- made print_command and print_simple_command void functions

builtins/common.c, builtins/common.h
	- builtin_error now a void function

	  the wrong character for the history event or word specifier

				    4/7

lib/readline/complete.c
	- make sure `max' is intialized to 0 when displaying the possible
	  completions, even if we've done `goto display_matches'

lib/posixheaders/stdc.h
	- if __STDC__ is defined but we're not using gcc (__GNUC__ not
	  defined), make `inline' expand to nothing

lib/readline/isearch.c
	- use STREQN to match the search string against the history line,
	  since we're not interested in exact matches, only matches of
	  the search string

				    4/8
				    ---
machines.h
	- description for a sparc running netbsd

				   4/11
				   ----
lib/readline/vi_mode.c
	- make sure we're starting an undo group when we implicitly
	  enter insertion mode after a command like c[motion], so
	  we can get to the characters that were inserted
	- new variable: vi_continued_command, set to 1 if we enter
	  insert mode implicitly

				   4/12
				   ----
machines.h
	- generic entry for MIPS machines running SVR4, SVR4.2
	- changed sony entry to handle M_MACHINE already being

	- fixes for malloc stats, from kboyce@bnr.ca

				   4/13
				   ----
machines.h
	- changed the u370/USGr4 description: added -DNO_SBRK_DECL to
	  SYSDEP_CFLAGS

lib/readline/readline.c
	- add a call to rl_set_keymap_from_edit_mode after reading the
	  inputrc file in readline_initialize_everything to override
	  the effect of any `set keymap' assignments in the inputrc
	  file

support/mksysdefs
	- added a check for MIPS RISCos machines
	- set the value of `dirlist' to /bsd43/usr/include if we're
	  building on a RISCos machine

lib/readline/bind.c
	- skip leading whitespace in lines read from the inputrc file
	  in rl_read_init_file

	- remove explicit inclusion of <sys/types.h>

machines.h
	- Xenix requires -DMEMMOVE_MISSING
	- Xenix 2.3 requires -DLD_HAS_NO_DASH_L
	- added #undef HAVE_RESOURCE to xenix descriptions just to be sure

cpp-Makefile
	- make sure texindex is built before trying to build the documentation

lib/doc-support/texindex.c
	- fixes for portability and to fit into the bash configuration
	  scheme

support/mksysdefs
	- fixed the Xenix section to make sure that sysdefs.h defines `i386'
	  for machines.h -- apparently the default xenix cc does not
	  predefine it

				   4/16
				   ----
shell.c
	- regularized parsing of `-c' option so it can be bundled with other
	  options
	- if bash is started with a `-o' without an argument, list the long

builtins/set.def
	- renamed `list_long_opts' to `list_minus_o_opts', made it global

builtins/common.c

	  terminate a substring search string.  This is more csh-like.

builtins/common.c
	- get_working_directory now uses get_name_for_error when for_whom
	  is null and it needs to print an error message

shell.c
	- set no_rc and no_profile in shell_reinitialize to clarify our
	  intent about not running the .bashrc for shell scripts

				   4/19

builtins/getopt.c
	- fix for core dump problems

parse.y, make_cmd.c, make_cmd.h, execute_cmd.c

lib/readline/readline.c
	- cleaned up some casts before xmalloc/xrealloc calls

	- set the keymap explicitly in init_terminal_io before trying to
	  bind the arrow keys

lib/readline/vi_keymap.c
	- bind ESC in vi_movement_keymap to 0 rather than rl_abort, since
	  the rl_abort binding keeps _rl_bind_if_unbound from working

shell.c
	- look in $PATH for an input file given on the command line only
	  if that file is not an `absolute program' (contains no slashes)

print_cmd.c
	- if the delimiter to a here document is supposed to be quoted,

	- make if statements and while/until statements print similarly,
	  with the then/do on the same line as the first word, separated
	  from the command list by a semicolon

make_cmd.c
	- reverse the order of patterns in the case statement pattern
	  list in make_pattern_list, so it's printed in the same way

	  in attempt_shell_completion

lib/readline/complete.c
	- set found_quote if a backslash is found in the string in

filecntl.h
	- moved to lib/posixheaders, replaced with symlink

support/getcppsyms.c
	- removed support for outputting -D__STDC__; it's rarely right

cpp-Makefile
	- build_builtins_in_dir(directory, makefile) --> build_builtins(target)
	  to get rid of the need to know how cpp does token concatenation

nojobs.c
	- changed the printing of the pid for asynchronous jobs to be the
	  same as sh (no brackets)
	- took a useless loop out of wait_for_background_pids

				   5/24
				   ----

cpp-Makefile
	- major surgery to replace #define with make variable assignments --
	  now cpp is used only for inclusion and conditionals (and shorthand)

machines.h
	- new entry for Lynx 2.1

builtins/declare.def
	- make sure that the name in command name=value is a legal variable
	  name (affects typeset/declare, export, readonly)

				   5/26
				   ----
machines.h
	- make sure a 386/486 running Solaris2 is not misidentified as a
	  Sun 386i
	- make sure a 486 running NeXT OS is identified as a `NeXT-i386'

				   5/27
				   ----
builtins/enable.def
	- fixed an off-by-one error in option parsing
	- improved option parsing to be Posix compliant (`--'), bad options

Makefile
	- call /bin/sh to run support/mksysdefs and create sysdefs.h, since
	  it's a shell script
	- ditto for $(CPPMAGIC)

cpp-Makefile
	- newversion.aux does not need to be linked against the math
	  library

				   5/30
				   ----
machines.h
	- set M_OS to `NeXTstep' for NeXT and i386 machines running NeXT OS

[1.14.2 beta release made available for FTP]

				   5/31
				   ----
siglist.h
	- don't define `strsignal' on SunOS5; it has its own

builtins/setattr.def
	- change set_or_show_attributes to check for legal variable names
