* 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.

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

* 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").

* doc/emacs/cmdargs.texi (Window Size X):
* doc/man/emacs.1.in: Be more vague about what the default height
is (bug#33921).

* doc/man/emacsclient.1: Mention that -n is ignored if --eval is
given (bug#20524).

* lib-src/etags.c: (compressors): Add zstd support.
(print_language_names): Report zstd support.
* doc/man/etags.1: Update doc.

2fcf2df Fix copyright years by hand
26bed8b Update copyright year to 2019
2814292 Fix value of default frame height.  (Bug#33921)

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

If the '--socket-name' argument is unspecified, the environment
variable 'EMACS_SOCKET_NAME' is now consulted with the same
semantics.  This mirrors the behavior of the '--server-file' argument,
and allows for easier configuration of emacsclient when the socket is
in a location other than 'TMPDIR' or '/tmp'.

* emacsclient.c (set_socket): Add support for the
EMACS_SOCKET_NAME environment variable.  (Bug#33095)

* misc.texi (emacsclient Options):
* emacsclient.1: Document the EMACS_SOCKET_NAME environment
variable.

* etc/NEWS: Announce the new feature.
