Remove our old ctags and suggest Universal Ctags instead.
This fixes a FIXME in lib-src/Makefile.in and speeds up compilation
quite a bit on my older CPU when I compile with --enable-gcc-warnings.
It also lessens installation and runtime footprint. (Bug#76322)
* .gitignore: Remove lib-src/ctags.
* admin/authors.el (authors-renamed-files-alist): Remove ctags.1.

If 'window-state-normalize-buffer-name' is non-nil, 'window-state-get'
will normalize stored buffer names, making them easier to restore for
users that use 'uniquify' buffer naming.
* doc/lispref/windows.texi (Window Configurations): Document
'window-state-normalize-buffer-name'.
* lisp/window.el (window-state-normalize-buffer-name): New defvar.
(window--state-normalize-buffer-name): New function.
(window--state-get-1): Call 'window--state-normalize-buffer-name'
rather than 'buffer-name'.

(Bug#76980)
Add more commands to 'eldoc-add-command-completions' to fix
disappearing ElDoc help in the minibuffer for the following
cases:
- All modes: Added "comment-indent-new-line".
- All modes: Added "delete-char" for handling when the user presses delete.
- Python mode: Added "python-indent-dedent-line-backspace" for handling
when the user presses backspace.
* lisp/emacs-lisp/eldoc.el (eldoc-remove-command-completions):
* lisp/progmodes/python.el (python-base-mode): Add more commands
to 'eldoc-add-command-completions'.
Copyright-paperwork-exempt: yes
* lisp/composite.el (composition-find-pos-glyph): New function.
* lisp/descr-text.el (describe-char): Use it to get the font glyph
code of "trivial" compositions.
(describe-char-display): Accept an additional optional argument
and use it as the font glyph code for the character.
* src/frame.c (Fmake_frame_invisible): In doc-string describe
effect on text terminals. Set FRAME correctly when called with
nil value. Make frame invisible before calling mru_rooted_frame
or next_frame.
(Ficonify_frame): Make it work for child frames on text
terminals
(Fmodify_frame_parameters): Make value 'icon' for 'visibility'
work for child frames.
* src/dispnew.c (frame_ancestors_visible_p): New function.
(frames_with_root): If VISIBLE_ONLY is non-nil, return only
frames whose ancestors are all visible to avoid that redisplay
draws visibly orphaned child frames.
* doc/lispref/frames.texi (Frames): Move descriptions of top
frame and 'tty-top-frame' here.
(Frame Layout): Mention that on text terminals the outer border
can be emulated by setting the 'undecorated' frame parameter.
(Frame Position, Frame Parameters, Window Frame Parameters)
(Position Parameters, Size Parameters): Rewrite sections dealing
with the handling of frame parameters in text terminals.
(Layout Parameters): Move description of 'undecorated' parameter
here. Clarify semantics of 'menu-bar-lines' parameter.
(Frame Interaction Parameters): Move description of 'visibility'
parameter here. Mention which parameters are not implemented on
text terminals.
(Mouse Dragging Parameters): Describe how these work on text
terminals.
(Visibility of Frames): Rewrite section.
(Raising and Lowering): Describe for text terminals.
(Child Frames): Fix description of 'iconify-child-frame' option.
* doc/emacs/programs.texi (Symbol Completion): Improve indexing by
adding "code completion". This is the name that this feature goes by
elsewhere, so users are likely to look for it.
EIEIO used to be developed externally as part of CEDET, but that is no
longer the case. It now has the same version as Emacs itself.
https://sourceforge.net/p/cedet/git/ci/8aa920380f8178ed2514f06f13c403d80db16752/
* lisp/emacs-lisp/eieio.el: Change "Version" header to "Old-Version".
(eieio-version): Make both the variable and the function obsolete in
favor of 'emacs-version'.
Make ediff cope with having some of its windows (especially the control
window) not shown by a custom ediff-window-setup-function.
Modernize relevant adjacent code. After this change, one can write a
custom ediff-window-setup-function that doesn't show the control window.
* doc/misc/ediff.texi (Notes on Heavy-duty Customization): Refine
language to explain that the window setup function doesn't have to show
all windows.
* lisp/vc/ediff-util.el (ediff-select-control-window-on-setup):
New variable.
(ediff-setup, ediff-recenter, ediff-recenter-one-window)
(ediff-recenter-ancestor, ediff-toggle-read-only)
(ediff-operate-on-windows, ediff-jump-to-difference-at-point)
(ediff-default-suspend-function)
(ediff-clone-buffer-for-region-comparison)
(ediff-clone-buffer-for-window-comparison): Modernize control flow;
select only windows that exist.
* lisp/vc/ediff-wind.el (ediff-with-live-window): New convenience macro.
(ediff-window-setup-function): Explain relaxed contract.
* lisp/minibuffer.el: Cut lines to fit into 80 columns.
(completion--insert-strings): Simplify `if` to `or`.
(completion--insert-horizontal, completion--insert-one-column):
Fix warning about used var starting with `_`. Avoid `apply-partially`.
From profiling, the main bottleneck in completion over large
completion sets is display-completion-list, when there are many
available candidates. For example, in my large monorepo, when
completing over the 589196 files or the 73897 branches, even
with the candidates narrowed down by typing some prefix to
complete, TAB (when it shows *Completions*) or ? is slow, mostly
in display-completion-list.
However, rendering all the completion candidates is unnecessary if
the *Completions* window is never scrolled to see those candiates. By
eagerly inserting only some candidates and lazily highlighting and
inserting the remaining candidates only when necessary, performance is
much improved.
* lisp/minibuffer.el (completion--insert-strings): Insert
completions lazily. (bug#74561)
(completions--lazy-insert-button): Add.
(completion--insert-horizontal, completion--insert-one-column):
Throw a continuation when enough lines of completions are
inserted.
(completion--insert-vertical): Add ignored lines argument.
(minibuffer-completion-help): Set completion-lazy-hilit.
(with-minibuffer-completions-window): Call
completion--lazy-insert-strings.
(with-minibuffer-completions-window):
* lisp/simple.el (completion-setup-function): Preserve
buffer-locals required for lazy completion insertion.
(switch-to-completions): Call completion--lazy-insert-strings.
* etc/NEWS: Announce.
* src/xdisp.c (move_it_in_display_line_to, display_line): When
considering the first glyph on a glyph row, take into
consideration the glyphs produced for line-number display.
(Bug#77065)
* lisp/hl-line.el (global-hl-line-modes): New user option.
(global-hl-line-highlight): Obey the new variable. (Bug#77022)
* etc/NEWS: Document new variable.
Fix possible wrong result of `string-pixel-width' with alternate
and default properties. Create new regression tests.
* lisp/emacs-lisp/subr-x.el (string-pixel-width): Like for
`face-remapping-alist', use in work buffer the value of
`char-property-alias-alist' and `default-text-properties'
local to the passed buffer, to correctly compute pixel width.
(Bug#77042)
* test/lisp/misc-tests.el: Add tests for `string-pixel-width'.
* test/lisp/progmodes/java-ts-mode-resources/indent.erts (Code):
Use `setq-local` and correspondingly move the remaining
assignment after activating the major mode.
Use 'view-mode-enter' instead of 'view-buffer' to ignore the 'special'
mode-class that prevents some modes from binding 'q' to 'exit-action'
that should call 'exit-recursive-edit' (bug#76745).
