* doc/misc/efaq.texi (Editing Windows files): Rename section from
"Editing MS-DOS files", and update the text to focus on Windows.
* doc/misc/efaq.texi (Colors on a TTY)
(Emacs does not display 8-bit characters): Mention MS-Windows before
MS-DOS.
These functions are documented in both `(elisp) Creating Strings' and
'M-x shortdoc RET string RET', so users will expect them to be available
without having to require 'subr-x'.
* lisp/emacs-lisp/subr-x.el (string-fill, string-limit, string-pad)
(string-chop-newline): Autoload.
* lisp/progmodes/grep.el (grep-read-files): Cease returning
some completion candidates unconditionally. Use
'completion-file-name-table' over 'read-file-name-internal'
because the latter uses 'completion-table-with-quoting', and
that doesn't blend well with other tables in
'completion-table-merge'.

To reproduce the problem:
0. emacs -Q
1. eval: (add-to-list 'major-mode-remap-alist '(c-mode . c-ts-mode))
2. C-x v L
3. in the *vc-change-log* buffer move point to the commit 20af58d3a1
4. type D
5. crash caused by diff-font-lock-syntax fontification that uses treesit
Emacs: 6f2036243f (2024-06-23, latest master)
Tree-sitter: 3da7deed (2024-06-08, version 0.22.6)
The immediate cause of the crash is that tree-sitter accessed a node's
tree, but the tree is already deleted. Commenting out the
ts_tree_delete line in treesit_ensure_parsed can "fix" the crash.
What happended, I think, is this:
1. Buffer modified, parser->need_reparse set to true,
parser->timestamp incremented.
2. A node is created from the parser, this node has the old tree but
the new timestamp (bad!).
3. Parser re-parses (treesit_ensure_parsed), new tree created, old
tree deleted.
4. Ftreesit_query_capture accessed the old node, and the old tree,
crash.
We shouldn't bump the parser timestamp when we set
parser->need_reparse to true; instead, we should bump the timestamp
when we actually reparsed and created a new tree.
* src/treesit.c (treesit_record_change): Don't bump parser timestamp.
