- history_do_write: use chown in the same way as history_truncate_file
11/12
-----
lib/readline/display.c
- expand_prompt: takes a new `flags' argument; only one flag defined
so far: PMT_MULTILINE
- expand_prompt: changed all callers to add new flags argument
- rl_expand_prompt, redraw_prompt: make sure to set PMT_MULTILINE in
FLAGS argument to expand_prompt if expanding parts of a prompt
containing embedded newlines
- expand_prompt: only add mode char to last line of a prompt with
embedded newlines, so mode indicator doesn't get lost and gets
updated properly. Fixes problem reported by Renlin Li

-----
lib/readline/display.c
- prompt_modestr: changed prompt_modechar to return a string denoting
the editing mode; default strings for emacs and both vi modes are
#defines in this file. prompt_modestr takes an argument in which
it returns the length of the mode string
- expand_prompt: if expanding mode strings in the prompt, get the
mode string to use and add it at the beginning of the prompt string,
before expanding it. This will allow future work allowing the mode
string to contain invisible characters

-----
lib/readline/rlprivate.h
- _rl_{emacs,vi_cmd,vi_ins}_mode_str: extern declarations for
variables to hold current values of user-settable mode strings;
variables to hold lengths
lib/readline/rlconf.h
- defines for default values of the mode strings for each editing mode
and keymap
lib/readline/display.c
- _rl_{emacs,vi_cmd,vi_ins}_mode_str: new variables to hold values of
user-settable mode strings
- _rl_{emacs,vi_cmd,vi_ins}_modestr_len: new variables to hold lengths
of corresponding mode string variables
- prompt_modestr: return appropriate user-settable mode string
variables
lib/readline/bind.c
- {emacs,vi-ins,vi-cmd}-mode-string: new user-settable mode string
variables
- sv_{emacs,viins,vicmd}_modestr: variable handling functions for user-
settable mode string variables. Non-null values are run through
rl_translate_keyseq so users can include invisible character
sequences in the mode strings; null values restore the default
- _rl_get_string_variable_value: handle values for new user-settable
mode string variables. Original code contributed by Dylan Cali
<calid1984@gmail.com>
lib/readline/doc/rluser.texi
- {emacs,vi-ins,vi-cmd}-mode-string: document, including the fact that
you can use \1 and \2 to bracket sequences of non-printing
characters
11/16
-----
lib/readline/history.c
- add_history: replace loop that copies history list down one item
with call to memmove to take advantage of whatever efficiencies
libc can offer. Won't be any slower than current loop
lib/readline/display.c
- rl_redraw_prompt_last_line: new function, calls redraw_prompt if
the prompt contains multiple lines; calls rl_forced_update_display
if not
lib/readline/readline.h
- rl_redraw_prompt_last_line: extern declaration, undocumented in
texinfo manual until I get it a little more work
bashline.c
- bash_execute_unix_command: instead of unconditionally calling
rl_forced_update_display, call rl_redraw_prompt_last_line if we
cleared the last line before executing the command. This keeps
commands that don't display any other output but just manipulate
the contents of the line buffer from redisplaying the prompt lines
before the last newline multiple times. Fixes bug reported by
Jesper Nygards <jesper.nygards@gmail.com> and Rob Foehl
<rwf@loonybin.net>. This means that commands that display output
will *only* display the final line of the prompt
- bash_execute_unix_command: if the command returns 124, we redraw
the line unconditionally, including all lines of the prompt
