`command-remapping'.
* keymaps.texi (Active Keymaps): Adapt description to use
`get-char-property' instead `get-text-property'. Explain how
mouse events change this. Explain the new optional argument of
`key-binding' and its mouse-dependent lookup.
(Searching Keymaps): Adapt description similarly. Explain the new
optional argument of `command-remapping'.
* Makefile.in (keymap.o): Add "keymap.h" and "window.h"
dependencies.
* keymap.c: include "window.h".
(Fcommand_remapping): New optional POSITION argument.
(Fkey_binding): New optional POSITION argument. Completely rework
handling of mouse clicks to get the same order of keymaps as
`read-key-sequence' and heed POSITION. Also temporarily switch
buffers to location of mouse click and back.
* keyboard.c (command_loop_1): Adjust call of `Fcommand_remapping'
for additional argument.
(parse_menu_item): Adjust call of `Fkey_binding' for additional
argument.
(read_key_sequence): If there are both `local-map' and `keymap'
text properties at some buffer position, heed both.
* keymap.h: Declare additional optional arguments of
`Fcommand_remapping' and `Fkey_binding'.
variable now defaults to Emacs's absolute file name, instead of
to "t".
* etc/PROBLEMS: Adjust tcsh advice for this.
* make-dist (EMACS): Exit and fail if the EMACS environment
variable is set to something other than an absolute file name.
* lisp/comint.el (comint-exec-1): Set EMACS to the full name of Emacs,
not to "t".
* lisp/progmodes/compile.el (compilation-start): Likewise.
* lisp/progmodes/idlwave.el (idlwave-rescan-asynchronously):
Don't use expand-file-name on invocation-directory, since this
might mishandle special characters in invocation-directory.
* man/faq.texi (Escape sequences in shell output): EMACS is now set
to Emacs's absolute file name, not to "t".
(^M in the shell buffer): Likewise.
* man/misc.texi (Interactive Shell): Likewise.
(__all__): Fix args -> eargs. Add new `modpath' fun.
(eargs): Add `imports' arg.
(all_names): New fun.
(complete): Rewrite without using rlcompleter.
Remove `namespace' arg, add `imports' arg.
(ehelp): Replace g and l args with `imports'.
(eimport): Use __main__ rather than `emacs' namespace.
(modpath): New fun.
