* doc/emacs/m-x.texi (M-x): Document it.
* doc/lispref/commands.texi (Interactive Call): Document it further.
* lisp/simple.el (read-extended-command-predicate): New user option.
(read-extended-command-predicate): Use it.
(completion-in-mode-p): New function (the default predicate).
* doc/lispref/functions.texi (Declare Form): Document the new
`completion' and `modes' declarations.
* lisp/simple.el (completion-with-modes-p): New helper functions.
* lisp/emacs-lisp/byte-run.el (byte-run--set-completion)
(byte-run--set-modes):
(defun-declarations-alist): New declarations for `completion' and
`modes'.
To scroll up/down the current displayed occurrence/error
without abandon the Occur/Grep buffer.
Add also a command 'recenter-other-window' to recenter
the other window from any kind of buffer.
* lisp/window.el (recenter-other-window): New command.
Bind recenter-other-window to S-M-C-l (Bug#46119).
* lisp/simple.el (recenter-current-error): New command.
* lisp/progmodes/grep.el (grep-mode-map):
Delete bidings for n and p.
* lisp/progmodes/compile.el (compilation-minor-mode-map):
Move here the n and p bindings.
Bind `recenter-current-error' to l.
* lisp/replace.el (occur-mode-map):
Same.
* doc/emacs/windows.texi (Other Window):
* doc/emacs/display.texi (Recentering):
Document recenter-other-window.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
Announce the changes.
* doc/lispref/positions.texi (Text Lines): Revert previous change.
* lisp/simple.el (line-number-at-pos): Remove definition.
* lisp/simple.el (count-lines): Revert back to using
`forward-line', because there seems to be a disagreement on how
lines should be counted in a region...
* src/fns.c (Fline_number_at_pos): Rename from
Fline_number_at_position and adjust parameter list.
* doc/lispref/positions.texi (Text Lines): Document it.
* lisp/simple.el (count-lines): Use it.
(line-number-at-pos): Ditto.
* src/fns.c (Fline_number_at_position): New function (bug#22763).
* simple.el (shell-command, shell-command-on-region): Set
revert-buffer-function buffer-locally, not globally. Also, avoid an
unnecessary call to (current-buffer) by taking advantage of the
closure (bug#46151).
* lisp/simple.el (previous-line-or-history-element): Move to the
beginning of minibuffer contents if there is editable minibuffer contents
on the same line after moving point to the prompt (bug#46033).
Fix minimal old-column from 0 to 1 to put point at the beginning of
minibuffer contents after going to the previous history element.
With `electric-indent-mode` enabled, `newline-and-indent` ends up indenting
3 times: once for the original line and twice on the new line.
`reindent-then-newline-and-indent` is even worse, indenting twice
both lines.
None of those commands should be affected by `electric-indent-mode`
since they even explicitly say in their name when and how they do
indentation.
(reindent-then-newline-and-indent): Temporarily disable
`electric-indent-mode` as well.
* lisp/simple.el (kill-visual-line): Use the 6th element of the
return value of 'posn-at-point', which provides the coordinates in
terms or row and column, and is thus more reliable for deciding
whether we moved to the next screen line. (Bug#45837)
* lisp/simple.el (kill-whole-line): Mention in the doc string that
this option affects 'kill-visual-line' as well.
(kill-visual-line): Improve the doc string. Delete the character
at which the line was wrapped under 'visual-line-mode'. Don't
indiscriminately delete whitespace following the wrap point.
(Bug#45837)
Give get-buffer-create an optional argument to inhibit buffer hooks
in internal or temporary buffers for efficiency (bug#34765).
* etc/NEWS: Announce new parameter of get-buffer-create and
generate-new-buffer, and that with-temp-buffer and with-temp-file
now inhibit buffer hooks.
* doc/lispref/buffers.texi (Buffer Names): Fix typo.
(Creating Buffers): Document new parameter of get-buffer-create and
generate-new-buffer.
(Buffer List, Killing Buffers): Document when buffer hooks are
inhibited.
(Current Buffer):
* doc/lispref/files.texi (Writing to Files): Document that
with-temp-buffer and with-temp-file inhibit buffer hooks.
* doc/lispref/internals.texi (Buffer Internals): Document
inhibit_buffer_hooks flag. Remove stale comment.
* doc/misc/gnus-faq.texi (FAQ 5-8):

* lisp/subr.el (generate-new-buffer): Forward new optional argument
to inhibit buffer hooks to get-buffer-create.
(with-temp-file, with-temp-buffer, with-output-to-string):
* lisp/json.el (json-encode-string): Inhibit buffer hooks in buffer
used.
* src/buffer.c (run_buffer_list_update_hook): New helper function.
(Fget_buffer_create): Use it. Add optional argument to set
inhibit_buffer_hooks flag instead of comparing the buffer name to
Vcode_conversion_workbuf_name. All callers changed.
(Fmake_indirect_buffer, Frename_buffer, Fbury_buffer_internal)
(record_buffer): Use run_buffer_list_update_hook.
(Fkill_buffer): Document when buffer hooks are inhibited. Use
run_buffer_list_update_hook.
(init_buffer_once): Inhibit buffer hooks in Vprin1_to_string_buffer.
(Vkill_buffer_query_functions, Vbuffer_list_update_hook): Document
when hooks are inhibited.
* src/buffer.h (struct buffer): Update inhibit_buffer_hooks
commentary.
* src/coding.h (Vcode_conversion_workbuf_name):
* src/coding.c (Vcode_conversion_workbuf_name): Make static again
since it is no longer needed in src/buffer.c.
(code_conversion_restore, code_conversion_save, syms_of_coding):
Prefer boolean over integer constants.
* src/fileio.c (Finsert_file_contents): Inhibit buffer hooks in
" *code-converting-work*" buffer.
* src/window.c (Fselect_window): Fix grammar. Mention
window-selection-change-functions alongside buffer-list-update-hook.
* test/src/buffer-tests.el: Fix requires.
(buffer-tests-inhibit-buffer-hooks): New test.
* lisp/simple.el (read-extended-command): Use 'affixation-function'
instead of 'annotation-function'. (Bug#45035)
(read-extended-command--affixation): New function created from
'read-extended-command--annotation'.
* lisp/simple.el: Specify comint-term-environment arglist in
function declaration.
(shell-command): Load shell.el before calling
comint-term-environment; otherwise it is undefined. Allow
async-shell-command-width to take precedence over the COLUMNS value
returned by comint-term-environment. (Bug#45034)
* lisp/simple.el (shell-command): Use the term environment from
comint, so that comint settings are used for commands like
`async-shell-command', too (bug#45034).
Copyright-paperwork-exempt: yes
* lisp/international/mule-cmds.el (mule--ucs-names-affixation):
Replace mule--ucs-names-annotation to display chars in prefixes
that implements two FIXME items.
(read-char-by-name): Let-bind completion-tab-width to 4.
Use affixation-function instead of annotation-function.
* lisp/minibuffer.el (completion-tab-width): New variable.
(completion--insert-strings): Align colwidth to tab positions
when completion-tab-width is non-nil.
* lisp/simple.el (completion-setup-function): Set tab-width to
completion-tab-width when completion-tab-width is non-nil.

yank after another yank.
* lisp/delsel.el: Put 'yank' property on yank-pop and yank-from-kill-ring.
* lisp/isearch.el (isearch-yank-pop): Use with-isearch-suspended
and read-from-kill-ring to read a string from the kill-ring and
append it to the search string.
* lisp/simple.el (yank-pop): Call yank-from-kill-ring and
read-from-kill-ring when last-command is not 'yank' instead of
signaling an error. Remove "*" from interactive spec. Update docstring.
(read-from-kill-ring): New function.
(yank-from-kill-ring): New command.

* lisp/emacs-lisp/lisp.el (delete-pair-blink-delay): New defcustom.
(delete-pair): Use it. (Bug#4136)
* lisp/simple.el (copy-region-blink-delay): New defcustom.
(indicate-copied-region): Use it. (Bug#42865)
Thanks to Sean Whitton <spwhitton@spwhitton.name>.
(indicate-copied-region): Use 'query-replace-descr' not to show
newlines literally. Use "Copied text" instead of misleading
"Saved text" (bug#42865).
* lisp/simple.el (goto-line): Rewrite to first find the position
of the line where to go, then later don't widen the buffer
when the found position is still inside narrowed part of buffer.
* lisp/isearch.el (isearch-message-prefix): Warn about narrowed buffer
in case of no more matches found.
Fix bug#44070, which causes the minibuffer display to jump upon minor edit
(redisplay_window): Obey it.
* lisp/simple.el (end-of-buffer): Obey it.
* test/src/xdisp-tests.el (xdisp-tests--in-minibuffer): New macro,
extracted from `xdisp-tests--minibuffer-resizing`.
(xdisp-tests--minibuffer-resizing): Use it.
(xdisp-tests--minibuffer-scroll): New test.
Don't call `syntax-propertize` from within narrowing
* lisp/progmodes/cperl-mode.el (cperl-forward-re): Revert last patch,
since it is now redundant.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-bug37127):
Remove unused var; fix test so it really catches the previous bug;
tweak the code to use mode-agnostic commands so it also works in `perl-mode`.
* lisp/progmodes/elisp-mode.el (xref-location-marker): Widen before going
to the found position.
* lisp/progmodes/etags.el (etags-goto-tag-location): Rerun after removing
narrowing.
* lisp/simple.el (goto-line-read-args): Use buffer-narrowed-p.

(next-error-found): Call the function.
* lisp/simple.el (visual-line-mode): Only save values once, even
if the mode is switched on twice (bug#43730). This makes both
previously set local values for variables like truncate-lines, as
well as default values for truncate-lines restorable.
* lisp/emulation/cua-base.el (cua-mode): Ditto.
* lisp/simple.el (goto-line-read-args): New function with code from goto-line.
(goto-line): New arg RELATIVE. Also use 'widen-automatically' to
leave all lines accessible in the narrowed buffer.
(goto-line-relative): New command.
* lisp/info.el (Info-mode-map): Remap 'goto-line' to 'goto-line-relative'.
* doc/emacs/basic.texi (Moving Point):
