last-repeatable-command.
(init_kboard): Initialize Vlast_repeatable_command.
(command_loop_1): Set it to real_this_command unless that was
bound to an input event.
(mark_kboards): Mark it.
(read_char_help_form_unwind): New function.
(read_char): Don't restore window configuration if a mouse click
arrives while the help form is being displayed.
(make_lispy_event): Don't generate Qsignal prefix for code 0.
Abort if signal code is unknown.
(store_user_signal_events): Don't make Qsignal prefix (code 0).
(Qsignal): Move declaration back to process.c.
(syms_of_keyboard): Don't intern or staticpro it here.
(some_mouse_moved): Return 0 if it is non-zero.
(make_lispy_event): Generate click event on mouse up if
ignore_mouse_drag_p is non-zero, even if mouse moved.
Clear ignore_mouse_drag_p on mouse down/up.
(read_avail_input): Store pending user signal events.
(struct user_signal_info): New struct.
(user_signals): New variable.
(add_user_signal, store_user_signal_events find_user_signal_name):
New functions.
(handle_user_signal): Move function from emacs.c. Don't store
USER_SIGNAL_EVENT here, but increment number of pending signals.
if first event in [signal xxx] sequence.
(lispy_user_signals, Qusr1_signal, Qusr2_signal): Remove.
(syms_of_keyboard): Don't intern and staticpro them.
(Qsignal, Qusr1, Qusr2): Declare.
(syms_of_keyboard): Intern and staticpro them.
(make_lispy_event): Return them for USER_SIGNAL_EVENTs.
`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'.
