* lisp/vc/diff-mode.el (diff--track-changes-function): Use the
new var.
* doc/lispref/text.texi (Tracking changes): Mention
`track-changes-undo-only`.
Zero-length strings are just 'empty'; 'null' can be confusing in several
ways.
* lisp/subr.el (split-string, string-lines):
* doc/lispref/strings.texi (Creating Strings):
Change argument names from 'omit-nulls' to 'omit-empty'.
* doc/lispref/strings.texi (Creating Strings):
* lisp/subr.el (split-string):
Make it clear that the SEPARATORS argument should not match the empty
string, since the behaviour was entirely an artefact of the original
implementation in this case; it makes little sense otherwise.
Clean up the examples for conciseness and do not waste space on
irrelevant details.
These produce the binary representation of a number.
'%#b' and '%#B' prefix with '0b' and '0B', respectively.

specs and add to comment on reconstructing the value with 'read'.

This experimental variable caused more trouble than it cured:
it was rarely used, and when used it tended to be used incorrectly.
* src/editfns.c (binary-as-unsigned): Remove. All uses removed.
Implement system GUI taskbar/dock/launcher icon badge, icon
progress indicator, icon attention alert features for D-Bus
platforms (tested on KDE and GNOME), NS (macOS/GNUstep),
MS-Windows.
Add 'progress-reporter-update-functions' abnormal hook to facilitate
taskbar progress display, and other custom progress reporters.
The default function list is 'progress-reporter-echo-area' which
is backward compatible.
* lisp/subr.el (progress-reporter-update-functions):
New defvar.
(progress-reporter-echo-area): New defun.
(progress-reporter-do-update): Run
progress-reporter-update-functions for both numerical and
pulsing reporters.

* etc/NEWS: Announce system-taskbar-mode. Announce progress
reporter callback enhancements.
The previous phrasing could be read as if backquote expansion were
mutable if containing substitions, but that is simply not true;
they should always be treated as non-mutable.
* doc/lispref/frames.texi (Font and Color Parameters): Fix
documentation of values of 'alpha-background'. Suggested by Jacob
S. Gordon <jacob.as.gordon@gmail.com>. (Bug#79861)
This fixes problems in some cases of out-f-tree builds
(bug#79694, bug#62099, bug#64806).
The use of true names in `load-history` dates back to to commits
33d74677e7 and 6bb6da3ec1 by Alan Mackenzie <acm@muc.de> in
May 24 2006, but that was reverted by Paul Eggert's commit
dff4f9c759 on Sep 18 2019.
* lisp/startup.el (command-line): Don't `file-truename` `lisp-directory`.
* src/lread.c (syms_of_lread) <load-history>: Adjust docstring,
to reflect the fact that the files there aren't "true names".
* doc/lispref/loading.texi (Hooks for Loading): Adjust accordingly.
Also massage the text to reflect the fact that nowadays features are
more common than file names as arguments to `with-eval-after-load`.
* doc/lispref/objects.texi (Equality Predicates):
Remove incorrect and/or misleading examples, add new ones,
and display them more compactly to save space.
Latest tree-sitter library throws a syntax error if the
predicate names in a query don't end with question mark. So we
made the following change:
:equal changed to :eq?
:match changed to :match?
:pred changed to :pred?
Old names are transparently converted to new names when
expanding patterns.
:match predicate can now take the regexp and the node in any
order: it'll figure out which is which automatically. This way
it works with current Emacs convention (regexp first), as well
as tree-sitter's match convention (regexp second).
* doc/lispref/parsing.texi (Pattern Matching): Update manuel to
use new predicate names.
* src/treesit.c:
(Ftreesit_pattern_expand):
(Ftreesit_query_expand):
(treesit_predicate_match):
(treesit_eval_predicates):
(syms_of_treesit): Use new predicate names.
* test/src/treesit-tests.el (treesit-query-api): Update test.
* src/frame.c (adjust_frame_size): Honor new option
'alter-fullscreen-frames'.
(syms_of_frame) <alter-fullscreen-frames>: New option to
maintain consistent state when attempting to resize fullscreen
frames. Default to 'inhibit' for NS builds because these
resized the frame while leaving the 'fullscreen' parameter alone
(Bug#79704).
(syms_of_frame) <Qinhibit>: Define symbol.
* lisp/cus-start.el (standard): Add customization options for
'alter-fullscreen-frames'
* doc/lispref/frames.texi (Frame Size): Describe new option
'alter-fullscreen-frames'.
* etc/NEWS: Call out new option 'alter-fullscreen-frames'.
* doc/lispref/commands.texi (Reading One Event): Mention
'read-char-choice-use-read-key'.
* lisp/emacs-lisp/rmc.el (rmc--show-help): Show non-selected
resized Help window at bottom. Inhibit useless message.
Remove unnecessary call to 'pop-to-buffer'.
(read-multiple-choice): Call 'read-multiple-choice--from-minibuffer'
when 'read-char-choice-use-read-key' is nil.
(read-multiple-choice--from-minibuffer): New function.
* test/lisp/emacs-lisp/rmc-tests.el (test-rmc--with-minibuffer-setup):
New macro.
(test-read-multiple-choice, test-read-multiple-choice-help):
Test both values of 'read-char-choice-use-read-key'.
* lisp/emacs-lisp/inline.el (define-inline): Add `noinline` declaration.
* doc/lispref/functions.texi (Inline Functions): Mention it.
* lisp/emacs-lisp/cl-macs.el (cl--do-arglist): Avoid %s for lists in
format string.
(cl-dolist, cl-dotimes): Remove obsolete optimization.
(cl-defstruct): Use `define-inline` instead of `cl-defsubst` for accessors.
* lisp/window-x.el (merge-frames): Rewrite doc-string. Error out
when FRAME1 and FRAME2 are not distinct frames.
(split-frame): Rewrite doc-string. Use 'user-error' instead of
'error'.
* doc/lispref/windows.texi (Changing Window Layouts): Document
'split-frame' and 'merge-frames'.
* etc/NEWS: Announce 'split-frame' and 'merge-frames'.
Some global minor modes require initialization. Those that are preloaded
currently abuse `custom-initialize-delay` for that, but it's suboptimal
and doesn't help those that aren't preloaded.
So introduce a new function to fill that need.
While at it, make `define-globalized-minor-mode` use it
automatically when useful.
* lisp/custom.el (custom-initialize-after-file-load): New function.
* lisp/tooltip.el (tooltip-mode):
* lisp/paren.el (show-paren-mode):
* lisp/rfn-eshadow.el (file-name-shadow-mode):
* lisp/epa-hook.el (auto-encryption-mode):
* lisp/minibuffer.el (minibuffer-regexp-mode, minibuffer-nonselected-mode):
* lisp/electric.el (electric-indent-mode): Use it instead of
`custom-initialize-delay` since the value does not depend on the
runtime context.
(electric-quote-mode): Don't use `custom-initialize-delay` since
the default value is nil anyway.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Automatically add `:initialize` if needed.
* lisp/emacs-lisp/eldoc.el (global-eldoc-mode): Remove `:initialize`,
now provided automatically.
* doc/lispref/customize.texi (Variable Definitions):
* doc/lispref/modes.texi (Defining Minor Modes): Document and Suggest
`custom-initialize-after-file-load` instead of `custom-initialize-delay`.
* doc/lispref/windows.texi (Window Hooks): Explain how to
discern calls for 'window-buffer-change-functions' where a
buffer was removed from the window from those where a buffer is
now shown in that window.
