Revert commit a218c98615, but in order
to avoid the spurious warnings that this commit tried to squash,
keep track of the vars used during the match so as to add
corresponding annotations to explicitly silence the spurious warnings.
To do this, we change the VARS used in `pcase-u` (and throughout
the pcase code): they used to hold elements of the form (NAME . VAL)
and now they hold elements of the form (NAME VAL . USED).
(pcase--expand): Bind all vars instead of only those found via fgrep.
(pcase-codegen): Silence "unused var" warnings for those vars that have
already been referenced during the match itself.
(pcase--funcall, pcase--eval): Record the vars that are used.
(pcase--u1): Record the vars that are used via non-linear patterns.

(ediff-even-diff-C, ediff-even-diff-Ancestor, ediff-odd-diff-A)
(ediff-odd-diff-B, ediff-odd-diff-C): Add :distant-foreground
"Black" for light background. For dark background
add :distant-foreground "White", and use darker shades of grey
for background colors (bug#46396).
* lisp/vc/vc-dir.el (vc-default-dir-printer): Add check for the
"ignored" status and make 'vc-dir-status-edited' the default face.
Also extend condition for more states that qualify as "warnings".
(vc-dir-ignored, vc-dir-status-ignored): Rename face for consistency.
* lisp/vc/vc-git.el (vc-git-dir-printer): Use the
'vc-dir-status-edited' as the default for the Git backend. And
reference the renamed face. Also stop treating the empty stash
differently from other header values.
* lisp/vc/vc-bzr.el (vc-bzr-dir-extra-headers): Implement new faces.
* lisp/vc/vc-cvs.el (vc-cvs-dir-extra-headers): Same.
* lisp/vc/vc-hg.el (vc-hg-dir-extra-headers): Same.
* lisp/vc/vc-svn.el (vc-svn-dir-extra-headers): Same.
This follows from the discussion in bug#46358.
* lisp/vc/ediff-init.el (ediff-hide-face): Redefine as obsolete
function alias for 'ignore'; the variable 'facemenu-unlisted-faces'
was removed in Emacs 22. Remove all calls.
* lisp/mh-e/mh-e.el: Add comment saying that the variable
'facemenu-unlisted-faces' is removed.
* lisp/vc/vc-dir.el (vc-dir-mode-map):
Remove the mouse-2 binding (bug#13692).
(vc-dir-mode): Update the docstring accordingly.
(vc-dir-status-mouse-map): New variable.
(vc-default-dir-printer): Use it on the state buttons.
* lisp/vc/vc-git.el (vc-git-dir-printer): Same.
Change calls from 'read-event' to 'read-key' in libraries expecting
mouse events. Do this only when 'xterm-mouse-mode' is enabled. That
way those libraries read decoded mouse events instead of the
underlying escape sequence. Add a parameter to 'read-key' that avoids
running any of the unbound fallbacks in 'read-key-sequence' so the
libraries can read mouse button-down events.
For backward compatibility purposes, the above logic is contained in a
new internal-only function: 'read--potential-mouse-event'.
* doc/lispref/commands.texi (Reading One Event): Document new
parameter to 'read-key'. Mention that non-character events on
terminals need 'read-key'.
* lisp/subr.el (read-key-full-map): Add new keymap used by 'read-key'.
(read-key): Add new parameter 'fallbacks-disabled' to prevent running
any of the unbound fallbacks normally run by 'read-key-sequence'.
(read--potential-mouse-event): Add new function that calls 'read-key'
or 'read-event' depending on if 'xterm-mouse-mode' is set.
* lisp/foldout.el (foldout-mouse-swallow-events):
* lisp/isearch.el (isearch-pre-command-hook):
* lisp/mouse-drag.el (mouse-drag-throw, mouse-drag-drag):
* lisp/mouse.el (mouse-drag-secondary):
* lisp/ruler-mode.el (ruler-mode-mouse-grab-any-column)
(ruler-mode-mouse-drag-any-column-iteration):
* lisp/strokes.el (strokes-read-stroke, strokes-read-complex-stroke):
* lisp/textmodes/artist.el (artist-mouse-draw-continously)
(artist-mouse-draw-poly, artist-mouse-draw-2points):
* lisp/vc/ediff-wind.el (ediff-get-window-by-clicking):
* lisp/wid-edit.el (widget-button--check-and-call-button)
(widget-button-click): Call 'read--potential-mouse-event' instead of
'read-event'.
* lisp/wid-edit.el (widget-key-sequence-read-event): Call 'read-key'
with 'fallbacks-disabled' set instead of 'read-event'. Unlike above
changes, this is unconditionally applied so it works for function
keys too. Apply 'local-function-key-map' instead of
'function-key-map' as that contains the full terminal translations.
* lisp/vc/ediff.el (ediff-windows): Use 'display-mouse-p' to check if
a mouse is available.
* src/lread.c (Fread_event): Recommend 'read-key' in docstring for
'read-event' for non-character events.
(log-edit-font-lock-keywords): Disable line-number display on
the thin separator line.
(log-edit-mode): Adjust `font-lock-extra-managed-props` accordingly.
(log-edit-changelog-entries): Don't use a nil buffer-local
`change-log-default-name`.
* lisp/vc/ediff-ptch.el (ediff-fixup-patch-map): Offer to create
the inferred file name (if it doesn't exist) (bug#8009). This allows
applying a patch that creates a file.
* lisp/vc/log-view.el (log-view-commit-body): Inherit from
font-lock-comment-face. This makes expanded commit messages in
log-view look the same as they did prior to commit 1f0b929430 (consult
bug#44424) (bug#44937).
Prefer vc-state to benefit from its caching (bug#44534)
This same technique is used in vc-git.el,
per commit 2018-06-28 "Remove extra process call from vc-git-find-file-hook"
93c41ce6aa.
* lisp/vc/vc-hg.el (vc-hg-registered): Use vc-state rather than vc-hg-state.
* lisp/vc/vc.el (vc-responsible-backend): Search through all the
VC backends instead of the first one, and choose the one that's
most specific (bug#42966).
* lisp/vc/vc.el (vc-revision-other-window): This function used to
change the current buffer, but this was changed in the previous
patch for indirect buffer support. Ensure that it still does
this, because this is what the callers expect (bug#44026).
