* src/xterm.c (x_set_frame_alpha): Don't synchronize while
setting alpha property, and don't ask for the current value of
the opacity property, which is much more expensive than changing
it.
By separating the code paths for append and vconcat, each becomes
simpler and faster.
* src/fns.c (concat_strings): Rename to...
(concat_to_string): ...this.
(concat): Split into concat_to_list and concat_to_vector.
(concat_to_list, concat_to_vector): New, specialised and
streamlined from earlier combined code.
(concat2, concat3, Fappend, Fconcat, Fvconcat): Adjust calls.
This is relevant for bug #56305, and might solve that bug. The code being
removed went into Emacs between 1992 and 1994, and looks to have been a
workaround for switching frames, before the command 'other-frame' had been
written. Nowadays, that code has harmful effects, causing frames' focus to be
redirected at random, sometimes back to the frame itself.
* src/frame.c (do_switch_frame): Remove 53 lines of code.
* lisp/net/net-utils.el (net-utils-machine-at-point)
(net-utils-url-at-point): Redefine as obsolete function alias for
'ffap-machine-at-point' and 'ffap-url-at-point'. Update callers.
* lisp/ffap.el (ffap-machine-at-point, ffap-url-at-point): Autoload.
* lisp/net/browse-url.el (browse-url-gnudoit-program)
(browse-url-gnudoit-args): Make obsolete. The corresponding command
'browse-url-w3-gnudoit' is already obsolete since 25.1.
* src/xterm.c (x_dnd_process_quit): New function.
(x_dnd_begin_drag_and_drop): Use it instead. Also quit if
quit-flag is true immediately after a selection converter is
run.
* lisp/net/net-utils.el (run-dig): Redefine in terms of `dig' and make
obsolete. (Bug#56432).
(dig-program): Delete duplicate defcustom; it is also in dig.el.
(dig-program-options): Move from here...
* lisp/net/dig.el (dig-program-options): ...to here.
(dig-invoke): Respect 'dig-program-options'.
(dig): Prompt for DNS server when given double prefix argument.
* lisp/simple.el (primitive-undo): If the visited-modtime of the
indirect buffer's file is bogus, use the modtime of the file
visited by its base buffer.
* src/undo.c (record_first_change): Call
'buffer_visited_file_modtime' with the correct buffer, instead of
always calling 'Fvisited_file_modtime', which returns possibly
bogus values for indirect buffers.
* src/fileio.c (Fset_visited_file_modtime): Signal a meaningful
error for indirect buffers.
(buffer_visited_file_modtime): New function, with implementation
taken from 'Fvisited_file_modtime'.
(Fvisited_file_modtime): Call 'buffer_visited_file_modtime'.
* src/lisp.h: Add prototype for 'buffer_visited_file_modtime'.
(Bug#56397)
The characters ऋ and ॠ are pronunced as ru in languages such as
Marathi, Gujarati, Telugu, etc. so add new translation rules that
reflects this sound. (bug#56414)
* lisp/language/ind-util.el (indian-itrans-v5-table): Add new
translation rules to make the input method more phonetic.
(indian-tml-base-table, indian-tml-base-digits-table): Fix typo.
* lisp/files-x.el (modify-dir-local-variable): Insert a newline
only after creating a new file.
(dir-locals-to-string): Remove newline to not add more newlines
on every save.
* lisp/files-x.el (dir-locals-to-string): Add newline at the end of
newly created .dir-locals.el files. This avoids git complaining about
"No newline at end of file".
* lisp/subr.el (set-transient-map): Add new args MESSAGE and TIMEOUT.
(set-transient-map-timeout, set-transient-map-timer): New variables.
* lisp/international/emoji.el (emoji-zoom-increase):
* lisp/indent.el (indent-rigidly):
* lisp/face-remap.el (text-scale-adjust, global-text-scale-adjust):
Use the arg MESSAGE of set-transient-map.
* doc/lispref/keymaps.texi (Controlling Active Maps): Mention new args
MESSAGE and TIMEOUT of set-transient-map.
* lisp/longlines.el (longlines-mode, longlines-encode-string): Update
from `buffer-substring-filters' to `filter-buffer-substring-function'.
Remove soft newlines in substring (bug#56335).
* lisp/window.el (fit-frame-to-buffer-sizes): Fix doc-string.
Give calls to 'max' a second argument so they do something
useful. If ONLY equals 'vertically', call
'window-text-pixel-size' with X-LIMIT nil (Bug#56102). For
minimum sizes of the window to fit, use 'window-safe-min-size' by
default.
* doc/lispref/windows.texi (Resizing Windows): Fix descriptions of
'fit-frame-to-buffer' and 'fit-frame-to-buffer-sizes'.
* msdos/sedlibmk.inp: Define GL_GNULIB_RAWMEMCHR.
* src/process.c (Fsignal_names): Disable on MS-DOS and use
SIGNUM_BOUND, which is always provided by gnulib.
