* doc/lispref/searching.texi (Regexp Special):
Mention char classes earlier, in a more-logical place.
Advise sticking to ASCII letters and digits in ranges.
Reword negative advice to make it clearer that it’s negative.

Avoid attempts to chain ranges, as this can be confusing.
For example, instead of [0-9-_.], use [0-9_.-].
* lisp/progmodes/bat-mode.el (bat-font-lock-keywords): Fontify
argument numbers in %~n. Suggested by Jostein Kjønigsen
<jostein@secure.kjonigsen.net> in emacs-devel.
* test/lisp/progmodes/bat-mode-tests.el
(bat-test-fontification-iter-var-1): Update the test to check also
the %~n construct.
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.
* lisp/progmodes/bat-mode.el (bat-font-lock-keywords): Match
word and symbol constituents when looking for variable names
to fontify; also, correct the syntax table and mark the equal
sign (=) character as punctuation. Improve fontification
accuracy of iteration/positional variables.
