input method.

if it is a keymap. (Bug#55393)
* etc/NEWS: Announce change in behavior of 'describe-keymap'.
* lisp/emacs-lisp/check-declare.el (check-declare-directory): Use
'directory-files-recursively' instead of running Find and Grep in
a subprocess. (Bug#55386)
* lisp/vcursor.el (vcursor-bind-keys, vcursor-key-bindings)
(vcursor-other-window): Drop OEmacs support. OEmacs was "a
version of GNU Emacs V19.19" that worked "under plain MSDOS,
Windows, or DESQview/X".
* lisp/emacs-lisp/ert-x.el (ert-with-temp-file): Accept a new
keyword argument :coding CODING to use as the encoding when
writing initial text to the temporary file.
* test/lisp/mail/undigest-tests.el (rmail-undigest-test-rfc934-digest)
(rmail-undigest-test-rfc1153-digest-strict)
(rmail-undigest-test-rfc1153-less-strict-digest)

help-fns--compiler-macro the last entry (because it's not the most
interesting information).

* lisp/help-fns.el (help-fns--compiler-macro): Also output data on
other byte compilation things, and link to the manual (bug#23264).
* lisp/net/eudc-bob.el (eudc-bob-can-display-inline-images): Make
into obsolete alias for display-graphic-p. Update all callers.
(eudc-bob-display-jpeg): Remove XEmacs compat code.
This is mostly factored out from tabulated-list.el (with bugs fixed).
* doc/lispref/modes.texi (Header Lines): Document it.

`with-temp-buffer-window', because that made the macro big and
difficult to understand.
(help--window-setup): Implement the relevant bits from
`with-temp-buffer-window'. Also don't clear out local variables,
because that makes things like `text-scale-mode' not work (bug#25979).
* doc/lispref/help.texi (Keys in Documentation): Document it.
* lisp/help.el (substitute-command-keys): Add an argument to
include menus in the \{...-map} output (bug#24236).
* lisp/dabbrev.el (dabbrev--find-expansion): Remove the now-dead
file name buffer from dabbrev--friend-buffer-list, so that we
don't trip over the killed buffer later (bug introduced in 2d0085f756).
* doc/emacs/programs.texi (Imenu): Remove documentation.
* lisp/imenu.el (imenu-flush-cache): Make into a function, since
this isn't supposed to be used interactively.
* lisp/progmodes/vhdl-mode.el (arch-alist, pack-alist)

expects them to be dynamically bound. (Bug#55389)
(vhdl-speedbar-insert-hierarchy): Rename the PACK-ALIST argument
to PACKAGE-ALIST, to avoid shadowing the global variable.
* etc/NEWS: Announce new arguments to `tooltip-show'.

`text-face' and `frame-face'. Use them to display text and
determine the foreground, background and border colors of the
