defconst's for the three maps. Add menus. Use "ses--" prefixes for
buffer-local variables. Use (point-min) instead of 1, even when we know the
buffer is unnarrowed. New function ses-read-number duplicates some code
from interactive "N" spec.
short to facilitate 16 bits wide bitmaps. Modify all standard
bitmaps accordingly.
(BYTES_PER_BITMAP_ROW, STANDARD_BITMAP_HEIGHT): New macros.
(FRBITS): Use STANDARD_BITMAP_HEIGHT instead of just sizeof.
(draw_fringe_bitmap): Ditto.
(init_fringe_bitmap) [MAC_OS]: Don't bitswap.
(init_fringe_bitmap) [HAVE_X_WINDOWS]: Enhance bitswapping to
handle up to 16 bits wide bitmaps.
(Fdefine_fringe_bitmap): Doc fix. Handle wider bitmaps.
(diff-regexp-alist, diff-old-file, diff-new-file)
(diff-parse-differences, diff-process-setup): Remove.
(diff-sentinel): New fun.
(diff): Use it. Run the process ourselves.
Use diff-mode for the rest of the processing.
(x_draw_fringe_bitmap): Handle overlayed fringe bitmaps;
thanks to YAMAMOTO Mitsuharu for advice on how to do this.
Use cursor color for displaying cursor in fringe.
(prolog-mode-syntax-table, prolog-mode-abbrev-table, prolog-mode-map):
Bring together declaration and initialization.
(prolog-mode-variables): Don't set the syntax table.
Don't set paragraph-start and comment-indent-function.
Add /*..*/ to the comment regexps.
(prolog-mode-commands): Remove. Do it during init of prolog-mode-map.
(prolog-mode-map): Don't bind TAB.
(prolog-mode): Set the syntax table.
(prolog-comment-indent): Remove.
(inferior-prolog-mode-map): Initialize in the declaration.
(inferior-prolog-mode-syntax-table)
(inferior-prolog-mode-abbrev-table): New vars.
(inferior-prolog-mode): Derive from comint-mode.
(run-prolog): Avoid switch-to-buffer which can fail in dedicated and
minibuffer windows.
Use cursor color for displaying cursor in fringe.
(x_redisplay_interface): Add null handlers for
define_fringe_bitmap and destroy_fringe_bitmap functions.
(left_bits, right_bits, up_arrow_bits, down_arrow_bits)
(continued_bits, continuation_bits, ov_bits, first_line_bits)
(last_line_bits, filled_box_cursor_bits, hollow_box_cursor_bits)
(bar_cursor_bits, hbar_cursor_bits, zv_bits, hollow_square_bits)
(fringe_bitmaps, draw_fringe_bitmap, draw_row_fringe_bitmaps)
(draw_window_fringes, compute_fringe_widths, update_window_fringes):
Move fringe handling vars and code to new file fringe.c.
(handle_display_prop): Handle left-fringe and right-fringe
display properties; store user fringe bitmaps in iterator.
(move_it_in_display_line_to): Handle cursor in fringe at eob.
(clear_garbaged_frames): Set force_flush_display_p if resized.
(redisplay_window): Redraw fringe bitmaps if not just_this_one_p.
(display_line): Handle cursor in fringe at eob.
(display_line): Set row user fringe bitmaps from iterator.
xterm.c to handle overlayed fringe bitmaps and to use cursor color
for displaying cursor in fringe.
(w32_define_fringe_bitmap, w32_destroy_fringe_bitmap): New W32
specific functions to define and destroy fringe bitmaps in fringe_bmp.
(w32_redisplay_interface): Add them to redisplay_interface.
(w32_term_init): Call w32_init_fringe instead of explicitly
defining fringe bitmaps in fringe_bmp array.
(x_delete_display): Call w32_reset_fringes instead of explicitly
destroying fringe bitmaps in fringe_bmp array.
xterm.c to handle overlayed fringe bitmaps and to use cursor color
for displaying cursor in fringe.
(x_redisplay_interface): Add null handlers for
define_fringe_bitmap and destroy_fringe_bitmap functions.
