				   ----
builtins/printf.def
	- new macro PC to call putchar and increment number of chars printed -
	  fixes bug in computation of value for %n format char
	- `tw' is now a global var so printstr can modify it using PC()
	- convert PF macro to use asprintf into a local buffer
	  Preparation for printf -v var
	- add code to add the text printed to a `variable buffer' if -v option
	  supplied.  The buffer grows as needed
	- printf now takes a `-v var' option to put the output into the variable
	  VAR rather than sending it to stdout.  It does not:
		print partial output on error (e.g., format string error)
		handle NULs in the variable value, as usual

				   3/16
				   ----
parse.y
	- fix bug in prompt string decoding that caused a core dump when PS1
	  contained \W and PWD was unset (null pointer deref)

builtins/printf.def
	- changed -v var behavior so it stores partial output into the named
	  variable upon an error

				   3/24
				   ----
lib/readline/bind.c
	- bool_to_int now takes a `const char *' argument

support/{printenv,recho,zecho}.c
	- include config.h
	- include "bashansi.h" for appropriate extern function declarations

configure.in
	- on MacOS X 10.4, compensate for loader not allowing static library
	  to override existing system dynamic library when compiling -dynamic
	  (affects readline and history libraries); so use absolute pathname
	  instead of -lreadline as library name

lib/glob/{glob,sm_loop,smatch}.c
	- make sure to cast arguments to (char *)  or (unsigned char *) as
	  appropriate to avoid gcc4 warnings

lib/glob/smatch.c
	- collsym (single-byte version) now takes a (CHAR *) first argument to
	  match callers; cast argument to strncmp appropriately

lib/sh/snprintf.c
	- fix ldfallback and dfallback to handle width and precision specs in
	  the format passed to sprintf()
	- fix STAR_ARGS macro to deal with negative field widths and precisions

				   3/25
				   ----
builtins/printf.def
	- since a negative precision in a "x.x[fFgGeE]" format specifier should
	  be allowed but treated as if the precision were missing, let it
	  through

lib/sh/snprintf.c
	- fix * code to deal with a negative precision by treating it as if
	  the `.' and any digit string in the precision had not been specified
	- fix format parsing code to deal with a negative inline precision,
	  e.g., "%4.-4f" by treating it as if the `'. and any digit string in
	  the precision had not been specified
	- a `+' in a format specifier should only act as a flag if it comes
	  before a `.' (otherwise it is ignored)

lib/readline/vi_mode.c
	- new function, rl_vi_rubout, to rl_rubout as rl_vi_delete is to
	  rl_delete; saves deleted text for possible reinsertion as with any
	  vi-mode `text modification' command (fixes problem with `X' reported
	  by [e-mail])

lib/readline/vi_keymap.c
	- bind `X' in vi command mode to rl_vi_rubout

lib/readline/funmap.c
	- add a bindable `vi-rubout' command, runs rl_vi_rubout

lib/readline/text.c
	- rewrote internals of _rl_rubout_char to make structure cleaner

lib/readline/{complete,text}.c
	- changed code to remove #ifdef HANDLE_MULTIBYTE where possible

				   3/28
				   ----
lib/readline/examples/rl.c
	- include <sys/stat.h> instead of posixstat.h if READLINE_LIBRARY not
	  defined

subst.c
	- fix mbstrlen to treat invalid multibyte sequences as sequences of
	  single-byte characters

				    4/8
				    ---
configure.in
	- default SIZE to `:' if cross-compiling and an appropriate size for
	  the target is not found

				   4/11
				   ----
subst.c
	- change match_upattern and match_wpattern to check whether or not the
	  supplied pattern matches anywhere in the supplied string, prefixing
	  and appending the pattern with `*' if necessary.  If it doesn't we
	  can short-circuit immediately rather than waste time doing up to
	  N-1 unsuccessful calls to strmatch/wcsmatch (which kills for long
	  strings, even if the pattern is short)

				   4/12
				   ----
configure.in
	- make sure the special case for MacOS X 10.4 only kicks in if the
	  `--with-installed-readline' option isn't supplied

lib/readline/{callback,readline,signals}.c
	- make sure rl_prep_term_function and rl_deprep_term_function aren't
	  dereferenced if NULL (as the documentation says)

builtins/mkbuiltins.c
	- don't bother with the special HAVE_BCOPY code; just use straight
	  assignments

builtins/ulimit.def
	- use _POSIX_PIPE_BUF in pipesize() if it's defined and PIPE_BUF is
	  not

				   4/13
				   ----
execute_cmd.c
	- add cm_function_def to the list of control structures for which
	  child processes are forked when pipes come in or out

				   4/14
				   ----
builtins/read.def
	- make sure the ^As added for internal quoting are not counted as
	  characters read when -n is supplied

				   4/20
				   ----
redir.c
	- fix redir_open so that the repeat open on failure that AFS support
	  adds restores the correct value of errno for any error message

				   4/26
				   ----

Makefile.in
	- make sure mksignames and mksyntax are invoked with the $(EXEEXT)
	  extension

				   4/28
				   ----
lib/readline/readline.h
	- new state variable: RL_STATE_CALLBACK, means readline is using the
	  callback interface

lib/readline/callback.c
	- set RL_STATE_CALLBACK in rl_callback_handler_install, unset in
	  rl_callback_handler_remove

				   4/29
				   ----
config-top.h
	- DONT_REPORT_SIGPIPE is now on by default, since it apparently
	  interferes with scripts

configure.in
	- arrange things so PGRP_PIPE is defined on Linux-2.4+ and version 3
	  kernels (ones that apparently schedule children to run before their
	  parent)

				   4/30
				   ----
builtins/caller.def
	- add call to no_options, so it can handle `--' option

doc/{bash.1,bashref.texi}
	- note explicitly that test, :, true, and false don't understand --
	  as meaning the end of options

				    5/7
				    ---
support/shobj-conf
	- darwin 8 needs the same LDFLAGS setting as darwin 7

parse.y
	- in save_parser_state, make sure we cast the return value from
	  xmalloc() to the right type
	- remove casts to (char *) in calls to yyerror()

lib/readline/signals.c
	- make SIGQUIT and SIGALRM code conditional on their definition
	- use raise() to send a signal if we don't have kill()

lib/readline/display.c
	- some MS-DOS and MINGW changes from the cygwin and mingw folks

config.h.in
	- add HAVE_PWD_H for <pwd.h>
	- add HAVE_FCNTL, HAVE_KILL for respective system calls
	- add HAVE_GETPW{ENT,NAM,UID} for passwd functions

configure.in
	- add check for <pwd.h>
	- add checks for fcntl, kill system calls
	- add checks for getpw{ent,nam,uid} C library functions
	- pass a flag indicating we're cross compiling through to
	  CFLAGS_FOR_BUILD in Makefile.in

lib/readline/complete.c
	- guard inclusion of <pwd.h> with HAVE_PWD_H
	- don't provide a missing declaration for getpwent if we don't have it
	- guard calls to {get,end}pwent with HAVE_GETPWENT

lib/readline/shell.c
	- guard inclusion of <pwd.h> with HAVE_PWD_H
	- guard inclusion of <fcntl.h> with HAVE_FCNTL_H
	- don't provide a missing declaration for getpwuid if we don't have it
	- guard calls to getpwuid with HAVE_GETPWUID
	- don't bother with body of sh_unset_nodelay_mode if we don't have
	  fcntl

	- guard inclusion of <pwd.h> with HAVE_PWD_H
	- guard calls to getpw{nam,uid} with HAVE_GETPW{NAM,UID}
	- guard calls to {get,end}pwent with HAVE_GETPWENT

Makefile.in,builtins/Makefile.in
	- @CROSS_COMPILE@ is substituted into CFLAGS_FOR_BUILD (equal to
	  -DCROSS_COMPILING if bash is being cross-compiled)

				    5/9
				    ---
aclocal.m4
	- print version as `0.0' in RL_LIB_READLINE_VERSION if the
	  `rl_gnu_readline_p' variable isn't 1 (accept no imitations)

				   5/11
				   ----
lib/readline/rlprivate.h
	- definition of a readline `search context', to be use for incremental
	  search initially and other types of search later.  Original from
	  Bob Rossi as part of work on incremental searching problems when
	  using callback interface

lib/readline/isearch.c
	- functions to allocate and free search contexts
	- function to take a search context and a character just read and
	  `dispatch' on it:  change search parameters, add to search string,
	  search further, etc.
	- isearch is now completely context-driven:  a search context is
	  allocated and passed to the rest of the functions

				   5/12
				   ----
lib/readline/isearch.c
	- an additional `isearch cleanup' function that can be called from
	  the callback interface functions when the search is to be terminated
	- an additional `isearch callback' function that can be called from
	  rl_callback_read_char when input is available
	- short-circuit from rl_search_history after initialization if
	  the callback interface is being used

lib/readline/callback.c
	- in rl_callback_read_char(), if RL_STATE_ISEARCH is set, call
	  _rl_isearch_callback to read the character and dispatch on it.
	  If RL_STATE_ISEARCH is unset when that call returns, and there is
	  input pending, call rl_callback_read_char() again so we don't
	  have to wait for new input to pick it up

support/shobj-conf,configure.in
	- add support for dragonfly bsd, the same as freebsd

				 5/13-5/15
				 ---------
lib/readline/callback.c
	- support for readline functions to `register' a function that will
	  be called when more input is available, with a generic data
	  structure to encapsulate the arguments and parameters.  Primarily
	  intended for functions that read a single additional character,
	  like quoted-insert
	- support for callback code reading numeric arguments in a loop,
	  using readline state and an auxiliary variable
	- support for callback code performing non-incremental searches using
	  the same search context struct as the isearch code

lib/readline/{callback,display}.c
	- if a callback function sets `_rl_redisplay_wanted', the redisplay
	  function will be called as soon as it returns

lib/readline/input.c
	- changes to _rl_read_mbchar to handle reading the null multibyte
	  character and translating it into '\0'

lib/readline/misc.c
	- break rl_digit_loop() into component functions that can be called
	  individually from the callback code more easily
	- share some of the functions with rl_digit_loop1() in vi_mode.c

lib/readline/readline.h
	- change the version #defines to reflect readline 5.1

lib/readline/search.c
	- break code into smaller functions that can be composed to work with
	  the callback code more easily

lib/readline/text.c
	- in rl_quoted_insert(), don't mess around with the tty signals if
	  running in `callback mode'

lib/readline/vi_mode.c
	- changed set-mark, goto-mark, change-char, and char-search to work
	  when called by callback functions

				   5/17
				   ----

lib/readline/rlprivate.h
	- new struct declaration for a `reading key sequence' context

lib/readline/readline.c
	- new variable, _rl_dispatching_keymap, keeps track of which keymap
	  we are currently searching
	- functions to allocate and deallocate contexts for reading multi-char
	  key sequences

				   5/18
				   ----
lib/readline/rlprivate.h
	- new struct defining a context for multiple-key key sequences (the
	  base case is escape-prefixed commands)

lib/readline/readline.c
	- change structure of _rl_dispatch_subseq to allow for callback code
	  to use it - rudimentary support for supporting the existing
	  recursion using a stack of contexts, each with a reference to the
	  previous
	- fix so that ^G works when in callback mode

lib/readline/callback.c
	- call the appropriate multiple-key sequence callback if the state is
	  set

				   5/19
				   ----
lib/readline/readline.c
	- broke code from _readline_internal_char after call to rl_dispatch
	  out into separate function:  _rl_internal_char_cleanup, callable by
	  other parts of the code
	- change _rl_internal_char_cleanup to unset _rl_want_redisplay after
	  it calls (*rl_redisplay_func)

lib/readline/callback.c
	- call _rl_internal_char_cleanup from rl_callback_read_char when
	  appropriate

				   5/24
				   ----
lib/readline/callback.c
	- use _rl_dispatch_callback and a chain of _rl_keyseq_contexts to
	  simulate the recursion used to decode multicharacter key sequences
	  (even things like ESC- as meta-prefix)
	- call setjmp in rl_callback_read_char to give things like rl_abort
	  a place to jump, since the saved location in readline() will not
	  be valid
	- keep calling _rl_dispatch_callback from rl_callback_read_char while
	  we are still decoding a multi-key key sequence
	- keep calling readline_internal_char from rl_callback_read_char while
	  we are reading characters from a macro

lib/readline/macro.c
	- use a slightly different strategy upon encountering the end of a macro
	  when using the callback interface:  when the last character of a
	  macro is read, and we are reading a command, pop the macro off the	
	  stack immediately so the loop in rl_callback_read_char terminates
	  when it should

lib/readline/readline.c
	- if longjmp() is called and we end up at the saved location whi
