* src/emacs.c (main): Mark the return from strerror as a constant,
since it shouldn't be changed (bug#43982).
* lib-src/movemail.c (pfatal_and_delete): Ditto.
Copyright-paperwork-exempt: yes
* doc/lispref/numbers.texi (Comparison of Numbers):
Copy some useful text from eql help string.
* src/fns.c (Feql): In doc string, say that eql also compares
integers by value.
* doc/lispref/internals.texi (Module Values): Document
make_unibyte_string (bug#34873).
* src/emacs-module.c (module_make_unibyte_string): New function.
(initialize_environment): Export it.
* src/module-env-25.h: Define it.
* test/data/emacs-module/mod-test.c (Fmod_test_return_unibyte):
Test it.
* test/src/emacs-module-tests.el (module/unibyte): Test it.
Fix mistakes made when removing Cocoa code from nsfont.m.
* src/nsfont.m (nsfont_draw): Remove spurious #ifdef.
(ns_uni_to_glyphs): The #if/#endif was removed from this code, but the
code itself not removed. Remove it now.

On a 32bit build, Emacs can otherwise crash with a !FIXNUM_OVERFLOW_P
assertion in `Ffont_info` by simply doing `emacs -Q` and then `C-s`.
* src/font.c: Try and detect uninitialized `max_width` fields.
(font_make_object): Set max_width to a silly value.
(Ffont_info): Check the value is not silly any more.
* doc/lispref/commands.texi (Command Loop Info):
`this-command-keys' does not include the C-u any more, so remove
that from the description and the example
(bug#22107).
* src/keyboard.c (Fthis_single_command_keys): Don't say that
`this-command-keys' returns the C-u prefix (bug#22111).
This makes it possible to run most of the redisplay code (tho not the
actual drawing since there's nowhere to draw) even when there's no
real frame at hand, as is the case in batch mode.
This makes `xdisp-tests--minibuffer-resizing` work even in batch.
(redisplay_internal): Obey it.
(init_xdisp): Set `echo_area_window` even in noninteractive mode.
* src/dispnew.c (update_frame): Skip the initial frame.
* src/frame.c (make_frame): Use 80x25 as the default initial size.
* test/src/xdisp-tests.el (xdisp-tests--minibuffer-resizing):
Use the new var and fix use of `executing-kbd-macro`.
* src/image.c (lookup_image): Make sure the frame's face cache
exists and has at least the basic faces. If FACE_ID is not a
basic face, and is no longer cached, fall back on the 'default'
face. (Bug#43700)

ce0842a165 * lisp/hi-lock.el (hi-lock-find-patterns): Autoload it. (...
* src/xdisp.c (restore_selected_window): Fix the more grave
problems caused by a function deleting the previously selected
frame or window (bug#39977).
* src/indent.c (scan_for_column): Accept 2 more arguments, and
report through them the position corresponding to PREVCOL. All
callers changed.
(Fmove_to_column): Use the prev_col's position to test for a TAB
instead of assuming that the TAB is just before point (which is
false when there's invisible text around). (Bug#43587)
* test/src/indent-tests.el: New file.
* src/cmds.c (internal_self_insert): Use FETCH_BYTE, not
FETCH_CHAR, for a decremented byte position (bug#41520).
* src/xdisp.c (Fwindow_text_pixel_size, trailing_whitespace_p): Ditto.
* src/fns.c (Fstring_search): Perform cheap all-ASCII checks before more
expensive ones. Use a faster loop when searching for non-ASCII
non-raw bytes.
* test/src/fns-tests.el (string-search): Add more test cases.
* src/print.c (print_object): When printing a unibyte string,
convert non-ASCII bytes to their character code, before sending
them to 'printchar'. (Bug#43632)
* src/nsimage.m (COLORSPACE_NAME): New macro to find the current
colorspace.
([EmacsImage initFromXBM:width:height:fg:bg:reverseBytes:]):
([EmacsImage initForXPMWithDepth:width:height:]): Use the current
colorspace.
* src/nsterm.h (NSAppKitVersionNumber10_7):
(NSAppKitVersionNumber10_10): Define for macOS version checks.
* src/nsterm.m ([NSColor colorForEmacsRed:green:blue:alpha:]): Tidy up
the version checking.
([NSColor colorUsingDefaultColorSpace]): Tidy the version checking and
use [NSColor colorUsingColorSpace:] with GNUstep.
The ns font backend is has been disabled on macOS for a long time and
doesn't work correctly even if re-enabled.
* src/nsfont.m:
(ns_char_width):
(ns_ascii_average_width):
(ns_get_covering_families):
(nsfont_open):
(nsfont_close):
(nsfont_draw):
(ns_uni_to_glyphs):
(ns_glyph_metrics):
(EmacsGlyphStorage): Remove all Cocoa only code.
* src/nsterm.h (EmacsGlyphStorage): Remove.
(struct nsfont_info): Make GNUstep only.
* src/nsterm.m (ns_compute_glyph_string_overhangs): Remove GNUstep
only code from Cocoa builds.
* src/nsterm.m (ns_clear_under_internal_border): New function.
(ns_after_update_window_line): Use the correct background color.
(ns_redisplay_interface): Add ns_clear_under_internal_border.
* src/xdisp.c (display_count_lines_visually): Bind
'display-line-numbers' to 'relative' around 'start_display' as
well, since that can invoke 'move_it_to' internally, thus
causing infinite recursion. (Bug#43589)
