Also make miscellaneous amendments.

* lisp/progmodes/cc-defs.el, lisp/progmodes/cc-engine.el
* lisp/progmodes/cc-langs.el, lisp/progmodes/cc-vars.el: Remove lots of
unneeded backslashes.
* lisp/progmodes/cc-langs.el (c-string-innards-re-alist): Remove redundant
"\\|\r" from regular expression.
* lisp/progmodes/cc-mode.el (c-make-mode-syntax-table): Correct the name of
the hook normal-erase-is-backspace-MODE-hook from a non-existant hook name.
This incorporates:

2019-09-23 Update URLs and associated text
* doc/misc/texinfo.tex, lib/open.c, lib/regcomp.c:
* lib/regex_internal.c, lib/regex_internal.h, lib/regexec.c:
* lib/stdio-impl.h:
Copy from Gnulib.
* lisp/help-mode.el (help-function-def--button-function): Factor
out into own function for easier reuse.
(help-function-def): ... from the lambda here.
* lisp/progmodes/sh-script.el (sh--maybe-here-document): Require a
space before expanding a heredoc (bug#3226). This allows the user
to insert a bash <<< "herestring", which was previously difficult.
* lisp/progmodes/cc-engine.el (c-before-change-check-<>-operators): Perform
checking now on an insertion, should point be inside a critical token.
(c-forward-<>-arglist-recur, c-guess-continued-construct): Check for <::, etc.
* lisp/progmodes/cc-langs.el (c-<-pseudo-digraph-cont-regexp)
(c-<-pseudo-digraph-cont-len): New lang variables/constants.
(map--into-hash): New function, extracted from `map-into <hash-table>`.
Speed it up a bit by using gethash instead of map-elt when we know
we're accessing a hash table.
* test/lisp/emacs-lisp/map-tests.el (test-map-into): Add corresponding test.
On visiting http://meltin.net/hacks/emacs/, we now find:
"I used to have some Emacs and Haskell hacks on my previous
sites. However, these hacks are now old and un-maintained. I don’t
think there is enough interest to keep them around."
* doc/misc/efaq.texi (Using an already running Emacs process):
Remove reference to obsolete package 'gnuserv'. (Bug#37574)
* lisp/simple.el (shell-command-prompt-show-cwd): New defcustom.
(async-shell-command, shell-command): Show current directory in prompt
when above option is non-nil. (Bug#4987)
* etc/NEWS: Announce it.
* lisp/window.el (switch-to-prev-buffer)
(switch-to-next-buffer): In doc-strings add links to
'prev-buffer' and 'next-buffer'.
(next-buffer, previous-buffer): Signal 'user-error' instead of
'error'. In doc-strings link to 'switch-to-prev-buffer' and
'switch-to-next-buffer'.
* lisp/window.el (window-default-font-height)
(window-default-line-height): New functions.
(fit-frame-to-buffer): Interpret values of MAX-HEIGHT and
MIN-HEIGHT arguments in terms of WINDOW's default line height
(Bug#37563).
(fit-window-to-buffer): Obey size restricting arguments even
when size of WINDOW's text does not change. Do not
temporarily select WINDOW and perform height/width related
calculations if and only if WINDOW is accordingly combined.
Interpret values of MAX-HEIGHT and MIN-HEIGHT arguments in
terms of WINDOW's default line height.
* doc/lispref/variables.texi (Creating Buffer-Local): Document the
new syntax for setq-local.
* lisp/subr.el (setq-local): Ensure that there's an even number of
variable/value pairs, and expand the doc string by taking some
text from `setq'.
* lisp/mwheel.el (mouse-wheel-follow-mouse): Doc fix.
(mouse-wheel--get-scroll-window): New function extracted from...
(mwheel-scroll): ...here.
(mouse-wheel-text-scale): New function to change face height in
the correct window, depending on the value of
'mouse-wheel-follows-mouse'. (Bug#28182)
(mouse-wheel-mode): Bind 'mouse-wheel-text-scale' instead of
'text-scale-increase' and 'text-scale-decrease'.
* time-stamp.el (time-stamp-format): Untabify the doc string, so
the two-column layout displays consistently in several contexts,
in particular when displayed by customize-variable.
* lisp/emacs-lisp/checkdoc.el (checkdoc-defun-info): Make checkdoc
work for cl-lib methods with more complex parameter lists
(bug#37063).
Copyright-paperwork-exempt: yes
* lisp/progmodes/compile.el
(compilation-transform-file-match-alist): New variable (bug#32968).
(compilation-error-properties): Use it to remove known false
positives.
(compilation-error-regexp-alist): Mention it in this doc string.
* lisp/tab-bar.el (tab-bar-tab-name-selected-window): Don't show the number
of windows when there is only one window in the window configuration.
(tab-bar-close-other-tabs): Rename from tab-close-other.
Take into account tab-bar-show to turn off when needed.
(tab-close-other): Alias to tab-bar-close-other-tabs.
* lisp/gnus/nnimap.el (nnimap-request-set-mark): Fix thinko in the
tick/read change: Unticking a message shouldn't make it unread,
but ticking it should make it read.
* lisp/gnus/mml-sec.el (mml-secure-epg-sign): Bug out if we
couldn't find anything to sign with instead of silently pretending
to sign.
* lisp/gnus/mml-smime.el (mml-smime-epg-sign): Don't bind
inhibit-display because that makes debugging impossible.
