- fix rl_message to use a dynamically-allocated buffer instead of a
fixed-size buffer of 128 chars for the `local message prompt'. Bug
report and fix from Micah Cowan <micah@cowan.name>

jobs.c
- add sentinel to wait_sigint_handler so it only sets wait_sigint_received
if waiting_for_child is non-zero; otherwise, it restores the old
SIGINT handler and sends itself the SIGINT
- set waiting_for_child around the calls to waitchld that use it to
synchronously wait for a process
- change logic that decides whether or not the child process blocked
or handled SIGINT based on whether or not waitpid returns -1/EINTR
and the shell receives a SIGINT and the child does not exit. If
the child later exits due to SIGINT, cancel the assumoption that it
was handled
- instead of testing whether or not the child exited due to SIGINT
when deciding whether the shell should act on a SIGINT it received
while waiting, test whether or not we think the child caught
SIGINT. If it did, we let it go (unless the shell has it trapped);
if it did not catch it, the shell acts on the SIGINT. Fix from
Linus Torvalds <torvalds@linux-foundation.org>, bug report originally

- initialize no_line_editing to 1 if READLINE is not defined -- we
can't have line editing without readline

lib/readline/signals.c
- add SIGHUP to the set of signals readline handles
lib/readline/doc/rltech.texi
- document that SIGHUP is now part of the set of signals readline
handles
lib/readline/input.c
- if _rl_caught_signal indicates that read() was interrupted by a
SIGHUP or SIGTERM, return READERR or EOF as appropriate
- call rl_event_hook, if it's set, if call to read in rl_getc
returns -1/EINTR. If rl_event_hook doesn't do anything, this
continues the loop as before. This handles the other fatal
signals
execute_cmd.c
- add a couple of QUIT; calls to execute_disk_command and
execute_simple_command to improve responsiveness to interrupts
and fatal signals
input.c
- rearrange getc_with_restart so that the return values from read()
are handled right
parse.y
- don't need to set terminate_immediately in yy_stream_get, since
getc_with_restart checks for terminating signals itself
- since readline returns READERR on SIGHUP or SIGTERM, don't need
to set terminate_immediately. Still doesn't handle other
signals well -- will have to check that some more
bashline.c
- new function, bash_event_hook, for rl_event_hook. Just checks for
terminating signals and acts on them using CHECK_TERMSIG.
- set rl_event_hook to bash_event_hook
builtins/read.def
- take out setting terminate_immediately; add calls to CHECK_TERMSIG
after read calls
doc/{bash.1,bashref.texi}
- move the text describing the effect of negative subscripts used to
reference indexed array elements to the paragraphs describing
${parameter[subscript]}, since that's where they are implemented.
Pointed out by Christopher F. A. Johnson <cfajohnson@gmail.com>
arrayfunc.[ch],subst.c
- array_expand_index now takes a new first argument: a SHELL_VAR *
of the array variable being subscripted. Can be used later to fully
implement negative subscripts
