'setopt-local' is the buffer local equivalent of 'setopt'.
Unify 'setopt', 'setopt-local', 'setq-local',
'buffer-local-set-state' with 'setq' to signal
'wrong-number-of-arguments'.
* lisp/cus-edit.el (setopt): Change error signal to
'wrong-number-of-arguments'.
(setopt-local): New macro.
(setopt--set-local): New function.
* lisp/subr.el (set-local): New function.
(setq-local, buffer-local-set-state): Signal
'wrong-number-of-arguments' rather than 'error'.
* doc/emacs/custom.texi (Examining): Document 'setopt-local'.
* etc/NEWS: Announce the new macro and function.
* lisp/progmodes/eglot.el (Version): Bump to 1.22.

* etc/themes/newcomers-presets-theme.el (newcomers-presets): Set
column-number-mode and compilation-scroll-output. Suggested by

Based on the existing grep-edit-mode code.
* lisp/progmodes/xref.el (xref-edit--prepare-buffer): New function.
(xref-edit-mode-map, xref-edit-mode-hook): New variables.
(xref-edit-mode, xref-change-to-xref-edit-mode)
(xref-edit-save-changes): New functions.
(xref--xref-buffer-mode-map): New binding ("e").
* doc/emacs/maintaining.texi (Identifier Search):
Mention xref-change-to-xref-edit-mode.
* etc/NEWS: Describe the addition.
The error messages are now displayed in a popped up buffer instead
of being output in the Dired buffer and signalling an error. The
file name bounds in Dired entries are now determined solely by the
offsets calculated by 'ls' with the --dired option and
consequently Dired now reliably recognizes file names that contain
a newline (bug#80499).
* etc/NEWS: Announce new Dired handling of errors from 'ls'.
* lisp/dired.el (dired-internal-noselect): Check Dired buffer for
file entries and if there are none kill the buffer to prevent
displaying a Dired buffer with no file entries.
(dired--ls-error-buffer): New variable.
(dired--display-ls-error): New function.
(dired, dired-other-window, dired-other-frame, dired-other-tab):
Use it to pop up buffer with error message emitted by 'ls'.
* lisp/files.el (insert-directory-clean): Remove the code that
treats lines beginning at column 0 in a Dired buffer as error
lines and consequently also remove the code using these lines to
adjust the offsets specifying the bounds of the file name in the
Dired entries. If the buffer contains a //DIRED-OPTIONS// line
output by --dired, delete this line even when it is at BOB.
(insert-directory): Remove the code that checks the return value
of 'ls' and signals an error based on that value. Write any error
message emitted by 'ls' to a temporary file and insert its content
into a buffer, which will be popped when invoking a Dired command
results in the 'ls' error. Adjust the comment above this function
to accommodate file names containing a newline in Dired entries.
(insert-directory-adj-pos): Remove this now unused function.
* test/lisp/dired-tests.el (dired-test-filename-with-newline-1)
(dired-test-filename-with-newline-2)
(dired-test-ls-error-message): New tests.
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Adjust test
to use of 'ls' error buffer instead of signaling an error.
This introduces the predicate frame-initial-p, which uses
struct frame.output_method or struct terminal.type to detect
initial_terminal without relying on its name (bug#80629).

Not a bug report, but this is from the emacs-devel thread
"Tree-sitter: Transcendental things".
Improve tree-sitter thing navigation functions to handle the
case where there are multiple nested parsers in the
buffer. Previously these functions just grab the node at point
and are limited to the parser of that node. Now these functions
will thoUrouly search through all parsers that covers point
before giving up.

* lisp/treesit.el (treesit--some): New macro.
(treesit--thing-sibling): Use the new macro, add a new PARSER
parameter.

(treesit-thing-at):
(treesit-navigate-thing): Use the new macro, add a new PARSER
parameter. Also pass the PARSER arg to recursive calls and
calls to treesit-thing-prev, etc.
