* buffer.c (Fmove_overlay): Delete an evaporating overlay
if it becomes empty after its bounds are adjusted to fit within
its buffer. Without this fix, in a nonempty buffer (let ((o
(make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
yields an empty overlay that has the evaporate property, which is
not supposed to happen.
* src/buffer.c (Fbuffer_local_variables)
(buffer_lisp_local_variables): Handle unbound vars correctly;
don't let Qunbound leak into Lisp.
* doc/lispref/variables.texi (Creating Buffer-Local): Minor clarification
to buffer-local-variables doc.
Fixes: debbugs:10715
This fixes a Y2038 bug on 64-bit hosts.
* buffer.c (reset_buffer):
* fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
(Fclear_buffer_auto_save_failure):
Use 0, not -1, to represent an unset failure time, since time_t
might not be signed.
(overlays_at, overlays_in, record_overlay_string, overlay_strings):
Don't update size of array until after memory allocation succeeds,
because xmalloc/xrealloc may not return.
src/buffer.c (init_buffer_once, syms_of_buffer): Set
bidi-display-reordering to t by default.
doc/emacs/mule.texi (Bidirectional Editing): Document the fact that
bidi-display-reordering is t by default.
lispref/display.texi (Bidirectional Display): Document the fact that
bidi-display-reordering is t by default.
* buffer.c (clone_per_buffer_values): Don't assume that
sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
This isn't true in general, and it's particularly not true
if Emacs is configured with --with-wide-int.
* buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
New macros, used in the buffer.c change.
* buffer.c (Qclone_number): Declare static and DEFSYM it.
(sort_overlays, overlay_strings): When an overlay's clone number
matches the window's clone number process the overlay even if
the overlay's window property doesn't match the current window.
(record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
(record_buffer): Remove unused local.
* frame.c (other_visible_frames, frame_buffer_list): Now static.
(set_frame_buffer_list): Remove; unused.
* frame.h (other_visible_frames): Remove decl.
* keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
* lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
(add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
if HAVE_GPM.
* menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
* process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
Define only if HAVE_GPM.
* widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
(update_hints_inhibit): Remove; never set. All uses removed.
* widgetprv.h (emacsFrameClassRec): Remove decl.
* window.c (delete_deletable_window): Now returns void, since it
wasn't returning anything.
(compare_window_configurations): Remove unused locals.
* xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
* xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
Omit no-longer-needed #ifdef USE_X_TOOLKIT, since USE_X_TOOLKIT is
implied by USE_GTK || USE_MOTIF.
(dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
the same widths as pointers. This follows up on the 2011-05-06 patch.
* xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
* xterm.h: Likewise.
(x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
