Replace some of the undefined characters with emulations of bidi
formatting characters and Niqud as per SI 1311-1.
(IT-unicode-translations): Ditto.
(IT-display-table-setup, IT-setup-unicode-display): Fill
characters without translations with dos-unsupported-char-glyph.
* src/macterm.c (init_font_name_table): Add an additional entry to
the font table with the script code smRoman for each Apple
Japanese font.
(XLoadQueryFont): Recognize a font as having the smRoman script
code even when FontToScript returns smJapanese if it is one of
those created above.
coding.type is coding_type_no_conversion or coding_type_raw_text,
use Fset_buffer_multibyte to make the buffer unibyte if REPLACE is
non-nil instead of just setting enable_multibyte_characters in the
buffer to nil.
(hexl-quoted-insert, hexl-self-insert-command)
(hexl-insert-hex-char, hexl-insert-decimal-char)
(hexl-insert-octal-char): Call it instead of hexl-insert-char.
Fix the doc strings accordingly.
(hexl-insert-char): Reject characters whose code is above 255.
Doc fix.
(hexl-mode-map): Copy the global keymap instead of creating a
sparse keymap, and bind all self-inserting characters to
hexl-self-insert-command.
(menu_face_changed_count): Variable removed.
(Finternal_set_lisp_face_attribute): Doc fix. If FRAME is t, set
the menu_face_changed_default flag, otherwise set the FRAME's
menu_face_changed_p flag if the `menu' face has been changed.
Prevent calling set_font_frame_param if FRAME is t.
(make_face_cache): Initialize cache's menu_face_changed_p
from menu_face_changed_default.
(realize_basic_faces): Look into the frame's face cache to
determine if the menu appearance needs updating.
Temporarily select EVENT's window for switching buffers.
(mode-line-bury-buffer): New function.
(mode-line-buffer-identification-keymap): Use it instead of
bury-buffer. Bind down-mouse events to prevent global down-mouse
events to shine through.
