handle memory exhaustion, it's better to return an error code to
them than to call abort.
(obtain): If we cannot allocate more memory, don't call
abort. Instead, return non-zero iff the allocation is successful.
(get_more_space): If obtain fails, return zero.
(get_bloc): Return zero if we can't allocate the new bloc.
(r_alloc_sbrk): Return zero if we can't allocate more memory.
(r_alloc): If we can't allocate more memory, set *PTR to zero and
return zero.
(r_re_alloc): If we can't allocate more memory, leave *PTR
unchanged, and return zero.
* ralloc.c (warnfunction): Renamed to warn_function; users changed.
macro, set Vlast_event_frame to Qmacro, instead of leaving it set
to the frame of the previous real event.
(read_key_sequence): If Vlast_event_frame isn't a frame, don't
bother switching buffers.
(syms_of_keyboard): Doc fix for Vlast_event_frame.
(Vlast_event_frame): Doc fix.
* keyboard.c (format_modifiers, reorder_modifiers): Handle the new
modifier bits.
down_modifier, drag_modifier): New modifiers, to support the new
input system. Re-arranged modifiers so that their bits are in
canonical order; this makes reorder_modifiers slightly simpler.
its `height' field; we may need to know the window's old buffer
once we have restored it from a window configuration.
Fset_window_configuration): When we restore a window, if its
`height' field is a buffer, restore its `buffer' field from that.
This allows us to leave the window's buffer unchanged if the
buffer recorded in the configuration is dead.
* window.c (delete_all_subwindows): Removed unused variable named
"count".
Qt.
* keymap.c (Fwhere_is_internal): Don't forget to advance map to
the next element when we find something that is neither a vector
nor a cons. Don't forget to QUIT in the appropriate places,
either.
(vc-log-after-operation-hook): New internal defvar.
(vc-checkin): Set vc-log-after-operation-hook to 'vc-checkin-hook.
(vc-finish-logentry): (run-hooks vc-log-after-operation-hook) at end.
(vc-update-change-log): When doing all visited files, remove directory
names from file names that are in default-directory.
(mouse-split-window-horizontally): New command.
Use S-mouse-2 for them.
(mouse-delete-window): Put on mode-line mouse-3.
(mouse-save-then-kill): New command, on mouse-3.
(mouse-delete-other-windows): Use @. Now on mode-line mouse-1.
(mouse-scroll-down, mouse-scroll-up): Use e, get line from event.
(mouse-scroll-move-cursor): Likewise.
(mouse-scroll-left, mouse-scroll-right): Likewise for column.
(mouse-scroll-move-cursor-horizontally): Likewise.
(keymap_table): Function removed; this function exists only to
support an incorrect understanding of the format of keymaps.
(access_keymap, store_in_keymap, Fcopy_keymap,
Faccessible_keymaps): Correctly handle vectors at any point in the
keymap; don't assume it must be at the front.
(describe_map): Instead of calling describe_vector on the vector
in the cadr of the keymap (if present) and then calling
describe_alist to do the rest, just call describe_map_2.
(describe_alist): Renamed to describe_map_2; call describe_vector
when we encounter a vector in the list.
* keymap.c (access_keymap, store_in_keymap): Clarify error message
for non-ASCII characters.
* keymap.c (access_keymap): Return the binding of Qt as the
binding for all unbound characters.
(create_process): #if 0 out the code which sets the child's
handler for SIGCHLD to sigchld; the code which gives sigchld its
value has been diked out under these CPP symbols, so this should
be diked out too.
set the subshell's priority to normal; nice doesn't return a
defined value on all systems. Instead, since emacs_priority gives
the priority that Emacs was nastied to, we can use it to reset the
priority in a straightforward way.
[BSD4_1], [USG], [VMS] (setpriority): Remove dummy and
compatibility definitions of setpriority.
