Eglot: tweak previous change (clear Flymake 'Wait' state)

When we don't have anything to give to Flymake, we still want to
signal we're alive so the mode-line doesn't show a confusing
'Wait'.

* lisp/progmodes/eglot.el (eglot--report-to-flymake): Clear 'Wait'
state.

; (completion--file-name-table): Minor cleanup.

Update tree-sitter subroutine in Fsubst_char_in_region

Some explanation: Fsubst_char_in_region used to have a branch,
one branch path calls replace_range, one branch path modifies
the buffer directly.  replace_range already calls
treesit_record_change within it, so we needed to make sure we
only call treesit_record_change in the other branch path.

After I added the call to treesit_record_change, some changes
are made to Fsubst_char_in_region, and the branch was removed.
So no wonder Stefan had the confusion and wrote the FIXME note.

Now that the branch is gone, we can indeed call
treesit_record_change in the end like signal_after_change.

* src/editfns.c (Fsubst_char_in_region): Move to end.

Improve env var handling in read-file-name

Fix various bugs, including bug#77718, by rewriting the way file
name completion handles environment variable expansion.  Instead
of using completion-table-with-quoting to manipulate the string
being completed on, simply make the completion table itself
understand substitute-in-file-name.

Tests are updated: partial-completion now preserves unexpanded
environment variables.  However, partial-completion no longer
works across environment variables containing delimiters; that's
an acceptable sacrifice.

Don't escape "." in `prin1' when followed by a letter

Among other users, let-alist widely uses symbols which start with a ".".
Make those symbols print more nicely by tweaking the escaping rules in
print_object to not escape a leading "." followed by a letter.  This is
a conservative change to avoid constraining future lexer changes.

This is a followup to 637dde4aba921435f78d0de769ad74c4f3230aa6, which
removed some unnecessary escaping of "." and "?" when printing symbols
in prin1.  (Actually, if we always escaped "?" (which was the case
before 637dde4aba92) then "." only ever needs to be escaped when
string_to_number returns non-nil.  So 637dde4aba92 could have just
dropped the escaping of "." with no other changes, if it didn't also
remove escaping of "?")

* src/print.c (print_object): Don't escape "." as the first
character in a symbol if followed by a letter. (bug#77656).
* test/src/print-tests.el (test-dots): Update for new behavior.

Improve syncing VC buffers before generating diffs

* lisp/vc/vc.el (vc-maybe-buffer-sync): Delete.  Correct
handling of indirect buffers is now implicitly achieved by
vc-buffer-sync-fileset.
(vc-buffer-sync-fileset): Make NOT-ESSENTIAL argument optional,
new MISSING-IN-DIRS optional argument.  Rewrite to handle
directories named in the fileset, not only files.

vc-buffer-sync-fileset.
(vc-root-diff): Similarly replace call to vc-maybe-buffer-sync.
This means the user is prompted to save additional buffers, that
they likely want to save before generating the diffs.
* test/lisp/vc/vc-misc-tests.el: New file.

vc-diff: Delete redundant call to vc-maybe-buffer-sync

This call is redundant with the subsequent call to
vc-buffer-sync-fileset.  I believe this call to
vc-maybe-buffer-sync was reintroduced by accident -- the
changeset adding the call to vc-buffer-sync-fileset deleted a
call to vc-sync-fileset in the same place.

* lisp/vc/vc.el (vc-diff): Delete redundant call to
vc-maybe-buffer-sync.
* lisp/files.el (find-buffer-visiting): Note in docstring that
this function only ever returns base buffers.

Improve help-fns-edit-variable for Lisp editing

Before d50c82f3e98e ("Simplify
'help-enable-variable-value-editing' using 'string-edit'"),
'help-fns-edit-variable' would open a buffer in 'emacs-lisp-mode'
and would not allow exiting that buffer with an invalid Lisp
expression.  Restore that functionality by enhancing 'string-edit'
to allow choosing a major mode and allow passing a function to
validate the buffer contents before returning.
* lisp/help-fns.el (help-fns-edit-variable): Call 'string-edit',
passing 'emacs-lisp-mode' and 'read'.
* lisp/textmodes/string-edit.el (string-edit--read): Add.
(string-edit): Add :major-mode and :read arguments and avoid
passive voice.
(read-string-from-buffer): Avoid passive voice in docs.
(string-edit-mode-map, string-edit-minor-mode-map)
(string-edit-mode, string-edit-minor-mode): Move 'string-edit'
keybindings to a minor mode.
(string-edit-done): Call 'string-edit--read' before exiting.
