Update some other copyright years automatically, by running:
Run 'UPDATE_COPYRIGHT_YEAR=2019 \
UPDATE_COPYRIGHT_USE_INTERVALS=1 \
UPDATE_COPYRIGHT_MAX_LINE_LENGTH=79 admin/update-copyright'
followed by 'admin/merge-gnulib'.

This incorporates mostly just copyright-year changes, plus
recent minor updates from glibc for the non-Emacs regular
expression code.

2fcf2dff Fix copyright years by hand
26bed8ba Update copyright year to 2019
28142925 Fix value of default frame height.  (Bug#33921)

* src/lisp.h (_UCHAR_T, UCHAR): Remove.  This workaround for
circa-1993 old-AIX has evidently not been needed for decades.
Tested on AIX 7.1, the oldest AIX version IBM still supports.

These are dates that admin/update-copyright did not update, or
updated incorrectly.

Run 'TZ=UTC0 admin/update-copyright $(git ls-files)'.

* lisp/net/tramp-sh.el (tramp-compute-multi-hops):
Reset `tramp-default-proxies-alist' in case of errors.

* doc/misc/tramp.texi (Ad-hoc multi-hops): Remove superfluous
first entry about %h and %u.  Describe, how to remove ad-hoc proxy
definitions.
(Cleanup remote connections): Mention, that also ad-hoc proxy
definitions are removed.

* etc/NEWS: Mention default host names in Tramp ad-hoc proxies.

These bugs were introduced after bignums were added.
* src/data.c (cons_to_unsigned, cons_to_signed):
* src/xdisp.c (calc_line_height_property):
Invoke integer_to_intmax and integer_to_uintmax only on integers.

In particular when the default comment type is currently line comments.  Do
this by setting font-lock-comment-end-skip.

* lisp/progmodes/cc-cmds.el (c-font-lock-comment-end-skip): New lang const.
(font-lock-comment-end-skip): New c-lang-setvar.

* src/window.c (save_window_save): When setting the marker
insertion type of saved window points treat a buffer local
value of 'unbound' for 'window-point-insertion-type' like
nil (Bug#33871).

* doc/emacs/cmdargs.texi (Window Size X): Fix value of default
frame height (Bug#33921).

* lisp/minibuffer.el (completion-category-defaults): Skip 'basic'
for 'project-file', in order not to prefer files at the top of the
directory tree.

* doc/lispref/files.texi (Unique File Names)
(Magic File Names, File Name Expansion): Improve documentation
of the "local part" of a remote file name.
* doc/lispref/processes.texi (Synchronous Processes)
(Asynchronous Processes): State explicitly that program and
file names passed to functions that start remote processes
need to be relative or obtained by 'file-local-name'.

* lisp/files.el (file-local-name):
* lisp/simple.el (start-file-process, process-file): Improve
the documentation of the "local part" of a remote file name,
and its use in APIs that start remote processes.

* lisp/emacs-lisp/rx.el (rx-check-any-string): Rewrite to handle raw bytes
in unibyte strings and accept LF as range endpoints (Bug#33205).
* test/lisp/emacs-lisp/rx-tests.el: Add tests for the above.

* lisp/net/tramp.el (tramp-eshell-directory-change):
Use `path-separator' as it does eshell.  (Bug#31704)

* lisp/eshell/esh-proc.el (eshell-gather-process-output): Do not
let `expand-file-name' prefix remote file names with MS Windows
volume letter.

* lisp/net/tramp.el (tramp-eshell-directory-change):
Use `path-separator' as it does eshell.  (Bug#31704)

* src/xdisp.c (format_mode_line_unwind_data): Before
temporarily selecting a window on another frame, separately save
the point of that window's buffer too.
(unwind_format_mode_line): After undoing the temporary
selection of a window on another frame, separately restore the
buffer point of that window.  This is needed since the
operation that deselects that window will have stored back the
point of that window into its buffer's point which is wrong
since that window was never "officially" selected (Bug#32777).

* lisp/files.el (cd): Support remote directory names on
MS-Windows.  (Bug#33791)

* lisp/wid-edit.el (group): Fix the :format spec.  (Bug#33566)

* lisp/progmodes/project.el (project--completing-read-strict):
Extract the common parent directory of all files first
(https://lists.gnu.org/archive/html/emacs-devel/2018-12/msg00444.html).

* src/nsterm.m (ns_draw_fringe_bitmap): Check the rectangle to clear
correctly.

* src/dispnew.c (buffer_posn_from_coords): Fix inaccuracies in
the commentary.

* lisp/play/gomoku.el (gomoku-terminate-game):
Don't make six-year-old children cry (Bug#33803).

Those have been supported by the function implementation since
commit 2014-03-31T12:06:34Z!dmantipov@yandex.ru (Bug#33807).
* lisp/emacs-lisp/bytecomp.el: substring has 1-3 args, not 2-3.

* doc/lispref/processes.texi (Accepting Output):
* src/process.c (Faccept_process_output):
Document that (accept-process-output P) can return non-nil
even after P has exited, and that it can return nil even if P
is still running (Bug#33839).

* build-aux/config.guess, lib/regcomp.c, lib/regex.c:
* lib/regex_internal.h, lib/regexec.c: Copy from Gnulib.

* src/dired.c (directory_files_internal): Make sure MATCH is
either nil or a string.  (Bug#33889)

* doc/misc/trampver.texi:
* lisp/net/tramp.el:
* lisp/net/trampver.el: Change version to "2.4.1".

* lisp/emacs-lisp/debug.el (debug): In noninteractive calls do
the buffer text truncation in the debugger buffer.

* lisp/vc/diff-mode.el (diff-refine-removed, diff-refine-added):
Change backgrounds in light backgrounds themes (bug#33567).

* lisp/gnus/message.el (message--rotate-fixnum-left): New function.
(message-checksum): Use it instead of assuming fixnum-only arithmetic.
This should fix Bug#33083.
