* src/haikufns.c: (struct user_cursor_bitmap_info):
(cursor_bitmaps): Fix hotspot for left arrow pointer.
(cursor_bitmaps_for_id): New array.
(haiku_set_mouse_color): If a color was specified, consult
`cursor_bitmaps_for_id' for user-specified cursors.
* src/haiku_support.cc (be_create_pixmap_cursor): New function.
* src/haiku_support.h: Update prototypes.
* src/haikufns.c (haiku_create_frame): Change default cursor
color to "font-color".
(haiku_create_tip_frame): Likewise.
(struct user_cursor_bitmap_info): New struct.
(cursor_bitmaps): New list of bitmaps corresponding to cursors.
(haiku_create_colored_cursor): New function.
(haiku_free_custom_cursors): Set current cursor to the default
cursor before freeing the original value.
(haiku_set_mouse_color): Actually recolor cursors based on
built-in bitmaps.
* src/haikuterm.c (haiku_defined_color): Clean up coding style.
This lets ‘./configure; make’ work on Fedora 36 x86-64 from a Git
checkout without generating false-alarm warnings.
* lib-src/etags.c (main): There appeared to be false alarm with
GCC 12. However, the code was wrong anyway, as it mishandled file
names containing "'" so fix that bug. This pacifies GCC.
(mercury_decl): Omit tests ‘s + pos != NULL’ that were apparently
intended to be ‘s[pos] != '\0'’ but which were miscoded to always
be true and which were mostly not needed anyway. In one place,
though, a test was needed, so fix that by using strchr instead.
* src/alloc.c (lisp_free) [!GC_MALLOC_CHECK]:
* src/term.c (Fsuspend_tty): Don’t look at a pointer after freeing
it, even just to test it for equality with some other pointer, as
this has undefined behavior in C and GCC 12 diagnoses this.
* src/dbusbind.c (xd_read_message_1): Rework the code a bit
so that it has fewer tests. This pacifies GCC 12 which was
complaining incorrectly about dereferencing a null pointer.
* src/intervals.c (copy_properties): Remove an eassume that should
no longer be needed even to pacify older GCCs, due to ...
* src/intervals.h (split_interval_left): ... this addition of
ATTRIBUTE_RETURNS_NONNULL to pacify a GCC 12 warning about
dereferencing a null pointer.
* src/regex-emacs.c (EXTEND_BUFFER): Use negative values rather
than auxiliary booleans to indicate null pointers. This pacifies
GCC 12 false alarms about using uninitialized variables.
* src/xdisp.c (clear_position): New function.
(append_space_for_newline, extend_face_to_end_of_line):
Use it to work around false alarms from GCC 12.
(display_and_set_cursor): Add an UNINIT to pacify GCC 12.
* src/xterm.c (x_draw_glyphless_glyph_string_foreground):
Defend against hypothetical bad code elsewhere;
this also pacifies GCC 12.
(x_term_init): Use fixed-size auto array rather than alloca,
as the array is small; this also pacifies GCC 12.
* src/haikuterm.c (haiku_draw_image_glyph_string): Merge cursor
foregrounds correctly.
(haiku_draw_hollow_cursor, haiku_draw_bar_cursor): New
functions. Port code from X.
(haiku_draw_window_cursor): Port code from X so bar cursors on
top of images are treated right.
* doc/lispref/buffers.texi (Buffer Modification): Adjust
documentation.
* src/buffer.c (Frestore_buffer_modified_p): Fix up the logic
around `autosaved': It means "the buffer is modified, and also
autosaved".
* doc/lispref/frames.texi (Pointer Shape): Document that the
pointer shape can now be changed on some window systems other
than X.
* lisp/term/haiku-win.el (x-pointer-X-cursor, x-pointer-arrow)
(x-pointer-bottom-left-corner, x-pointer-bottom-right-corner)
(x-pointer-bottom-side, x-pointer-clock, x-pointer-cross)
(x-pointer-cross-reverse, x-pointer-crosshair)
(x-pointer-diamond-cross, x-pointer-hand1, x-pointer-hand2)
(x-pointer-left-side, x-pointer-right-side)
(x-pointer-sb-down-arrow, x-pointer-sb-left-arrow)
(x-pointer-sb-right-arrow, x-pointer-sb-up-arrow, x-pointer-target)
(x-pointer-top-left-corner, x-pointer-top-right-corner)
(x-pointer-top-side, x-pointer-watch, x-pointer-invisible): New
pointer constants.
* src/haiku_support.cc (BCursor_from_id): Accept int instead of
enum.
* src/haiku_support.h: Update prototypes.
* src/haikufns.c (haiku_create_frame): Stop manually assigning
cursors and set default value of the mouse color property.
(haiku_free_frame_resources): Free custom cursors too.
(struct user_cursor_info, INIT_USER_CURSOR): New struct.
(haiku_free_custom_cursors): New function.
(haiku_set_mouse_color): New param handler.
(haiku_frame_parm_handlers): Add param handler.
(syms_of_haikufns): New cursor shape variables from X.
* src/haikuterm.h: Update prototypes.
* lisp/avoid.el (mouse-avoidance-random-shape): Ignore invisible
pointer.
(mouse-avoidance-ignore-p): Adjust for interprogram DND.
* lisp/term/x-win.el (x-pointer-invisible): Make value larger
than the maximum possible glyph.
* src/xfns.c (x_set_mouse_color): Use function that handles
`x-pointer-invisible' too.
* src/xterm.c (x_create_font_cursor): New function. Handle
invisible cursors.
* src/xterm.h: Update prototypes.
* src/haiku_support.cc (FlipBuffers): Only set view bitmap if it
actually changed.
* src/haikuterm.c (haiku_clip_to_string_exactly)
(haiku_draw_window_cursor, haiku_draw_fringe_bitmap): Fix region
invalidation.
* haiku_support.cc (class EmacsFontSelectionDialog)
(UpdateStylesForIndex): If a style was previously selected and
exists in the new family as well, select it after adding the new
items.
* haikuterm.c (haiku_calculate_relief_colors): Calculate
backgrounds for image glyphs like on X.
(haiku_draw_relief_rect): Remove extra parameter.
(haiku_draw_string_box, haiku_draw_image_relief): Adjust
accordingly.
* lisp/simple.el (get-scratch-buffer-create): New function, factored
out of scratch-buffer, and additionally clearing the modification flag
and calling substitute-command-keys (bug#55257).
(scratch-buffer):
* lisp/server.el (server-execute):
* lisp/startup.el (normal-no-mouse-startup-screen, command-line-1):
* lisp/window.el (last-buffer, window-normalize-buffer-to-switch-to):
* src/buffer.c (Fother_buffer, other_buffer_safely): Use it.
(syms_of_buffer): Add Qget_scratch_buffer_create.
* lisp/startup.el (startup--get-buffer-create-scratch): Delete
now-unused function.
* doc/lispref/os.texi (Summary: Sequence of Actions at Startup):
* NEWS (Incompatible changes in Emacs 29.1): Document the change.
* doc/lispref/buffers.texi (Buffer Modification): Document
buffer-modified-p returning `autosaved'.
* lisp/subr.el (with-silent-modifications): Use
restore-buffer-modified-p instead of altering the buffer modiff
(since this has other side effects like not updating after async
`display' changes.
* src/buffer.c (Fbuffer_modified_p): Allow returning whether the
buffer has been autosaved after changes.
(Frestore_buffer_modified_p): Allow adjusting whether the buffer
has been autosaved after changes.
* src/fileio.c (Fdo_auto_save): Refill the doc string.

alpha safer.

changes.
* src/xterm.h (struct x_output): New flag `alpha_identical_p'.
* src/dispnew.c (update_text_area): New parameter `partial_p'.
Set it if not enough glyphs were drawn to determine if a row
doesn't have a stipple.
(update_window_line): Preserve current_row->stipple_p in that
case, after making the desired row current.
* src/xterm.c (x_draw_fringe_bitmap): Set row->stipple.
* lisp/net/browse-url.el (browse-url-default-browser): Use that
