Remove our old ctags and suggest Universal Ctags instead.
This fixes a FIXME in lib-src/Makefile.in and speeds up compilation
quite a bit on my older CPU when I compile with --enable-gcc-warnings.
It also lessens installation and runtime footprint. (Bug#76322)
* .gitignore: Remove lib-src/ctags.
* admin/authors.el (authors-renamed-files-alist): Remove ctags.1.
* admin/check-man-pages: ctags.1 is no longer a special case.
* admin/quick-install-emacs (PUBLIC_LIBSRC_BINARIES): Remove ctags.
* cross/Makefile.in (LIBSRC_BINARIES): Remove lib-src/ctags.
* doc/man/ctags.1, lib-src/ctags.c: Remove.
* java/Makefile.in (CROSS_LIBSRC_BINS): Remove ctags.
* lib-src/Makefile.in (INSTALLABLES): Remove ctags${EXEEXT}.
(ctags${EXEEXT}): Remove.
* lib-src/etags.c (CTAGS): Remove. All uses replaced by ...
(ctags): ... this new static var.
(STDIN): Remove macro. All uses replaced by new STDIN_OPTION constant.
(CTAGS_OPTION, STDIN_OPTION): New contants.
(longopts): New --ctags option.
(ctags_default_C_help): New constant,
to override default_C_help at runtime.
(default_C_help): Now always the etags version.
(C_LANG_NAMES_INDEX): New macro.
(print_language_names): Do not assume etags.
(PROGRAM_NAME): Remove. All uses removed.
(print_help): Document --ctags if PRINT_UNDOCUMENTED_OPTIONS_HELP.
(main): Support new --ctags option, and support all [ce]tags options.
* test/manual/etags/Makefile (CTAGS_PROG):
Now etags --ctags, since there is no longer a ctags.
This adds '--no-fallback-lang' and '--no-empty-file-entries'
options, and their opposites '--fallback-lang' and
'--empty-file-entries'.
* lib-src/etags.c (fallback_lang, empty_files): New toggles.
(main): Initialize them to 'true'.
(longopts) [!CTAGS]: Add the '--(no-)fallback-lang' and
'--(no-)empty-file-entries' options.
(find_entries): If 'fallback_lang' is false, don't attempt Fortran
and C/C++ fallbacks.
(print_help): Add help for new options.
(main): If 'empty_files' is false, don't output file entries for
files that have no tags. (Bug#73484)
* doc/emacs/maintaining.texi (Create Tags Table):
* etc/NEWS:
* doc/man/etags.1: Document the new options.
* test/manual/etags/Makefile (check): Add test for new options.
* test/manual/etags/ETAGS.good_7: New file.
* doc/man/ebrowse.1:
* doc/man/emacs.1.in:
* doc/man/emacsclient.1:
* doc/man/etags.1: Add 'time-stamp-time-zone' to local variables to
prefer UTC when generating timestamp.
This fixes check-man-pages warnings such as:
troff: doc/man/etags.1:203: warning: escape character ignored before '='
* doc/man/etags.1: Fix groff warnings.
* lib-src/emacsclient.c (DEFAULT_TIMEOUT): New constant.
(timeout): New static variable.
(longopts, shortopts, decode_options, print_help_and_exit): Add new
flag --timeout.
(set_socket_timeout, check_socket_timeout): New helper functions.
(main): Display a status message or exit after Emacs has not responded
for a while, depending on above new --timeout flag. (Bug#50849)
* doc/emacs/misc.texi (emacsclient Options):
* doc/man/emacsclient.1: Document the above new option.
* etc/NEWS: Announce it.

22a832ad82 Mention the #f syntax from cl-prin1
3fd0854378 Fix file name quoting in tramp-smb.el (do not merge)
* doc/emacs/misc.texi (emacsclient Options): Document the new option.
* doc/man/emacsclient.1: Mention the new option (bug#51374).
* etc/NEWS: Mention the new option.
* lib-src/emacsclient.c (reuse_frame): New variable.
(longopts): New option.
(decode_options): Decode the new option.
(print_help_and_exit): Document the new option.
(main): Use the new option.
Tag declarations starting lines with ':-'.
By default, all declarations are tagged. Optionally, first
predicate or functions in clauses can be tagged as in Prolog
support using '--declarations'. (Bug#47408).
* lib-src/etags.c (test_objc_is_mercury, Mercury_functions)
(mercury_skip_comment, mercury_decl, mercury_pr):
Implement Mercury support. As Mercury and Objective-C have
the same file extension .m, a heuristic test tries to detect
the language.
* doc/man/etags.1: Document the change. Add Mercury-specific
behavior for '--declarations'. This option tags first
predicates or functions in clauses in addition to declarations.
* lib-src/etags.c (Rust_functions): New function to make tags for rust
files.
(Rust_help, Rust_suffixes): New constant.
* doc/emacs/maintaining.texi (Tag Syntax): Add Rust item.
* doc/man/etags.1: Add Rust (bug#46055).
* doc/man/ebrowse.1:
* doc/man/emacs.1.in:
* doc/man/emacsclient.1:
* doc/man/etags.1: Update date to match last significant change. Set
file local variable time-stamp-pattern. Fix title line to match the
recommendations in "man man-pages".
Ref: https://lists.gnu.org/r/emacs-devel/2020-09/msg01002.html
* doc/man/emacs.1.in: Fix syntax of --script argument. The Info
manual states that --script has to be followed by a space, and the
syntax with the equals sign doesn't actually work.
* lisp/startup.el (x-apply-session-resources): Enable tab-bar-mode
when X resource "tabBar" class "TabBar" is "on", "yes" or "1".
* doc/man/emacs.1.in:
* doc/emacs/xresources.texi (Table of Resources):
Document X resource "tabBar" (class "TabBar").
