* test/lisp/align-tests.el (align-regexp): New test.
* test/lisp/align-resources/align-regexp.erts: New file.
* test/lisp/align-resources/c-mode.erts: Add new test case.
When displaying the completion candidates, show how the face would
look with the new foreground/background.
* lisp/faces.el (faces--string-with-color): New helper,
factored out from 'defined-colors-with-face-attributes'.
(defined-colors-with-face-attributes): Use it.
(read-color): Add optional argument FACE and pass
it to 'faces--string-with-color.'
(read-face-attribute): Call 'read-color' with more appropriate
foreground and face arguments.
* doc/lispref/minibuf.texi (High-Level Completion): Describe
the intention behind the arguments FOREGROUND and FACE of
'read-color'. (Bug#64725)
Subroutine names are fontified as subroutine names even if the name is also
the name of a builtin (fixing an ancient unreported bug). Subroutine name
are just comments in comment and pod (fixing a bug introduced recently)
* lisp/progmodes/cperl-mode.el (cperl-init-faces): Move
fontification of sub declarations before that of builtins. Don't
override existing faces when fontifying subroutine declarations.
Don't fontify method calls even if the sub names match those of
builtins.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-fontify-sub-names):
New tests with a subroutine name in several surroundings.
* test/lisp/progmodes/cperl-mode-resources/sub-names.pl: New resource
for the new test.
* lisp/progmodes/ruby-mode.el (interpreter-mode-alist): Don't hardcode
ruby version. This adds support for modern versions of Ruby like
"ruby2.7", instead of the previously hardcoded "ruby1.9".
* lisp/emacs-lisp/rx.el:
Add tables of legacy syntax.
(rx--translate-symbol):
Translate the legacy construct `not-wordchar` as (not wordchar), which
is more intuitively obvious.
* lisp/emacs-lisp/rx.el (rx--translate-syntax):
Generate the shorter \w and \W instead of \sw and \Sw.
* test/lisp/emacs-lisp/rx-tests.el (rx-atoms, rx-syntax, rx-not):
Adapt tests.
* lisp/emacs-lisp/rx.el (rx--generate-alt):
Treat the intervals and classes lists separately without joining,
to reduce allocation. Handle special cases first.
(rx--union-intervals):
Implement directly instead of using intersection and complement.
* test/lisp/emacs-lisp/rx-tests.el (rx-any): Adapt test, as some
character alternatives are now slightly different.
(rx--complement-intervals, rx--union-intervals)
(rx--intersect-intervals): New unit tests.
* lisp/textmodes/conf-mode.el (conf-toml-mode): Do not use case
folding when font locking.
* test/lisp/textmodes/conf-mode-tests.el (conf-test-toml-mode):
Expand test.
* test/lisp/textmodes/conf-mode-tests.el (conf-test-javaprop-mode):
Attempt to give the test some meaning by repairing regexps,
and fixing it so that it passes.
This is no longer recommended in 2023, and in any case seems like
overkill in an otherwise bare-bones HTML5 template.

* lisp/net/tramp-sh.el (cl-seq): Require.
(tramp-perl-file-truename): Print also whether the file is a symlink.
(tramp-bundle-read-file-names): Rename from
`tramp-vc-registered-read-file-names'. Print also the
`file-directory-p: value.
(tramp-sh-handle-make-symbolic-link): Combine two commands. Use
`tramp-skeleton-make-symbolic-link'.
(tramp-sh-handle-file-truename): Read also "file-symlink-marker"
property.
(tramp-sh-handle-file-directory-p): Simplify if-let clause.
(tramp-sh-handle-file-name-all-completions): Simplify command.
(tramp-bundle-read-file-names): New defun.
(tramp-sh-handle-vc-registered, tramp-get-remote-path): Use it.
(tramp-open-shell): Flush "scripts" connection property.
(tramp-open-connection-setup-interactive-shell): Combine two commands.
* lisp/net/tramp-smb.el (tramp-smb-handle-make-symbolic-link):
* lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-make-symbolic-link):
Use `tramp-skeleton-make-symbolic-link'.
* lisp/net/tramp.el (tramp-skeleton-make-symbolic-link): Rename from
`tramp-skeleton-handle-make-symbolic-link'.
(tramp-handle-file-symlink-p): Check file property
"file-symlink-marker".
* lisp/language/vietnamese.el (vietnamese-vscii): Update docstring.
(vietnamese-tcvn, tcvn, tcvn-5712): Make them aliases of
vietnamese-vscii.
("Vietnamese"): Drop vietnamese-tcvn from coding-system values.
Update docstring.
* etc/NEWS: Announce this change.
