Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
If font-lock-mode is disabled in the current buffer, and
there are no matches for REGEXP, then keep FACE available
for a next search.
* lisp/hi-lock.el (hi-lock-set-pattern): Add FACE into
hi-lock--unused-faces if font-lock-mode is disabled and
there are no matches.
* test/lisp/hi-lock-tests.el (hi-lock-test-set-pattern): Add test.
* lisp/hi-lock.el (hi-lock-set-pattern): If REGEXP is already
highlighted, then push FACE into hi-lock--unused-faces (Bug#26666).
* test/lisp/hi-lock-tests.el (hi-lock-bug26666): Add test.
Problem reported by Artur Malabarba in:

Most of these fixes are to documentation; many involve fixing
longstanding quoting glitches that are independent of the
recent substitute-command-keys changes. The changes to code are:
* lisp/cedet/mode-local.el (mode-local-augment-function-help)
(describe-mode-local-overload):
Substitute docstrings before displaying them.
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
Quote the generated docstring for later substitution.
Mostly these fixes prevent the transliteration of apostrophes
that should stay apostrophes. Also, prefer curved quotes in
Bahá’í proper names, as that’s the preferred Bahá’í style and
these names are chock-full of non-ASCII characters anyway.
* lisp/emacs-lisp/eieio-core.el (eieio-defclass-autoload)
(eieio-defclass-internal):
* lisp/emacs-lisp/eieio.el (defclass):
* lisp/hi-lock.el (hi-lock-mode):
Don’t transliterate Lisp apostrophes when generating a
doc string or diagnostic.
* lisp/international/mule-diag.el (list-coding-systems-1):
* lisp/international/ogonek.el (ogonek-jak, ogonek-how):
* lisp/mail/sendmail.el (sendmail-query-user-about-smtp):
* lisp/vc/ediff-mult.el (ediff-redraw-registry-buffer):
* lisp/vc/ediff-ptch.el (ediff-fixup-patch-map):
Substitute quotes before putting them in the help buffer.
