This simplifies time conversions in other time zones.
It also prevents display-time-world tampering with TZ (Bug#21020).
* admin/admin.el (add-release-logs):
Use improved add-log-time-format API.
* admin/merge-gnulib (GNULIB_MODULES): Add time_rz, timegm.
(GNULIB_TOOL_FLAGS): Avoid flexmember, setenv, unsetenv.

Emacs no longer uses HAVE_TZALLOC directly.
* doc/lispref/os.texi (Time of Day, Time Conversion)
(Time Parsing):
* etc/NEWS: Document the new behavior.
Merge from gnulib, incorporating:
2015-07-25 strftime: fix newly-introduced bug on Solaris
2015-07-23 fprintftime, strftime: use timezone_t args
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

Fix race when current-time advances while we're running.

(emacs_localtime_rz, emacs_mktime_z, xtzalloc, xtzfree)
(tzlookup): New static functions.
(init_editfns): New arg DUMPING. All uses changed.
(init_editfns): Omit most initialization if dumping, not if
!initialized. Initialize wall_clock_tz and local_tz.
(emacs_nmemftime, format_time_string): Time zone argument can now
be any time zone, not just a boolean for UTC or local time. All
callers changed.

deletion of last element.
* lisp/textmodes/flyspell.el
(flyspell-check-previous-highlighted-word): Really accept a
numeric argument, as the doc string describes. Fix an off-by-one
error in looking up overlays, so invocation with point immediately
after a word would check that word. Clarify the doc string as
Suggested by N. Jackson <nljlistbox2@gmail.com>. (Bug#21129)
* lisp/skeleton.el (skeleton-read): Allow PROMPT to be a function.
* lisp/textmodes/sgml-mode.el (sgml-attributes, sgml-value): Pass

Copyright-paperwork-exempt: yes
* lisp/textmodes/flyspell.el (flyspell-correct-word-before-point)

controlled via the keyboard.

Add "tab0" to stty call.
* test/automated/tramp-tests.el (tramp-persistency-file-name):

as our callers expect. This was clobbered as part of fixing
bug#5673. (Bug#21107)

instead of `xref-location'.

of `xref-location'.

http://lists.gnu.org/archive/html/emacs-devel/2015-07/msg00213.html
* lisp/info.el (Info-find-node-2): Reset the buffer's encoding to
'undecided', so that it is set to the encoding of the Info file we
are about to insert. Otherwise, 'info-apropos' will fail to find
some index nodes in some UTF-8 encoded files, if the buffer's
previous encoding is Latin-N or some such.
* lisp/info.el (Info-read-subfile): Add to the returned value the
length of subfile preamble, after converting it to file's byte
offset, as expected by the caller. Use bufferpos-to-filepos.
(Info-find-node-2): If searching for a node with a
1000-character slop fails, try again with a 10000-character slop,
to account for known bugs in Texinfo 5.0 and 5.1. (Bug#21055)

function.

* epg-config.el (epg-gpgconf-program): New variable.
* epg.el (epg--start): Call `pinentry-start' if
allow-emacs-pinentry is set in ~/.gnupg/gpg-agent.conf.

xref-find-references. Declare functions `grep-read-files' and
`grep-expand-template'.
(xref--read-identifier): Show the default value in the prompt.
* lisp/progmodes/xref.el (xref-find-regexp): When called with
prefix argument, ask for file patterns to search as well. When
prompting for the directory, require an existing one.

above function.
* lisp/progmodes/project.el (project-ignores): New generic
function, and an implementation for the VC project type.
* lisp/progmodes/xref.el (xref--rgrep-command): Split, as a
variant of rgrep-default-command that handles a generic list of
