This incorporates:
2015-07-27 time_rz: port better to MinGW
2015-07-27 time: port __need_time_t to MinGW
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/strftime.c, lib/time.in.h, lib/time_rz.c: Copy from gnulib.
* lib/time-internal.h: New file, from gnulib.
* nt/mingw-cfg.site (ac_cv_header_pthread_h)
(gl_cv_sys_struct_timespec_in_pthread_h): Force to "no", to avoid
picking up 'struct timespec' from pthread.h, if it is installed on
the user's system. We want either the definitions from MinGW
system headers, if available, or the Gnulib replacements if not.
* nt/inc/ms-w32.h <struct timespec>: Don't define, as we now use
lib/time.h.
* lib/time.in.h: Don't let __need_* symbols affect what happens on
MinGW. These symbols are defined by MinGW system headers, but we
don't want that to affect whether Gnulib portions of the header
are or aren't used.
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.
* configure.ac (tzalloc): Remove test for this, since
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.
* lib/strftime.c, lib/strftime.h, lib/time.in.h, m4/sys_time_h.m4:
* m4/time_h.m4:
Update from gnulib.
* lib/time_rz.c, lib/timegm.c, m4/time_rz.m4, m4/timegm.m4:
New files from gnulib.
* lisp/time-stamp.el (time-stamp-string):
* lisp/time.el (display-time-world-list)
(display-time-world-display):
Use new API, with time zone arg.
* lisp/time.el (display-time-world-display):
Fix race when current-time advances while we're running.
* lisp/vc/add-log.el (add-log-iso8601-time-zone)
(add-log-iso8601-time-string): Accept optional time zone arg.
* lisp/vc/add-log.el (add-change-log-entry):
* lisp/vc/log-edit.el (log-edit-changelog-ours-p): Use new arg.
* nt/gnulib.mk: Propagate lib/gnulib.mk changes here.
Add rules for the time module, since they're now needed
for tzalloc etc.
* src/conf_post.h (getenv_TZ, setenv_TZ): New macros.
(emacs_getenv_TZ, emacs_setenv_TZ): New decls.
* src/editfns.c: Include errno.h.
(set_time_zone_rule): Omit unnecessary forward decl.
(initial_tz): Remove, replacing with ...
(local_tz, wall_clock_tz, utc_tz): New static vars and constants.
(tzeqlen): New constant; prefer it to (sizeof "TZ=" - 1).
(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.
(Fformat_time_string, Fencode_time, Fcurrent_time_string)
(Fcurrent_time_zone): New optional arg ZONE.
(Fdecode_time, Fset_time_zone_rule): ZONE arg can now also take
the same form as with the other new additions.
(decode_time_zone): Remove; no longer needed.
(tzvalbuf): Now file-scope.
(emacs_getenv_TZ, emacs_setenv_TZ): New functions.
(syms_of_editfns): Define Qwall.
* src/editfns.c (mktime_z) [!HAVE_TZALLOC]:
* src/systime.h (mktime_z, timezone_t, tzalloc, tzfree)
[!HAVE_TZALLOC]:
Remove; now supplied by gnulib.
* src/emacs.c (main):
* src/lisp.h (init_editfns): Adjust to init_editfns API change.
* lisp/subr.el (delete-consecutive-dups): Work even if the last
element is nil (Bug#20588). Avoid rescan of a circular list in
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)
* test/automated/tramp-tests.el (tramp-test31-*, tramp-test32-*):
Implement using the documented interface
`tramp-connection-properties', rather than with internal functions.
* lisp/skeleton.el (skeleton-read): Allow PROMPT to be a function.
* lisp/textmodes/sgml-mode.el (sgml-attributes, sgml-value): Pass
lambdas to `skeleton-read' (bug#20386).
Copyright-paperwork-exempt: yes
* lisp/textmodes/flyspell.el (flyspell-correct-word-before-point)
(flyspell-emacs-popup): Require neither a GUI frame nor mouse
support, since pop-up menus work with text terminals and can be
controlled via the keyboard.
* doc/emacs/fixit.texi (Spelling): Mention Flyspell commands that
can be invoked via the keyboard. Mention those commands by name
and add them to the fn index. (Bug#21125)
* lisp/net/tramp-sh.el (tramp-open-connection-setup-interactive-shell):
Add "tab0" to stty call.
* test/automated/tramp-tests.el (tramp-persistency-file-name):
Set to nil.
(tramp--test-hpux-p): New defun.
(tramp--test-utf8): Use it.
* lisp/ffap.el (ffap-url-at-point): Set ffap-string-at-point-region,
as our callers expect. This was clobbered as part of fixing
bug#5673. (Bug#21107)
(ffap-gopher-at-point): Set ffap-string-at-point-region.
* lisp/progmodes/xref.el (xref--match-buffer-bounds): New
function, extracted from xref-pulse-momentarily.
(xref-query-replace): New command.
(xref--query-replace-1): New helper function.
(xref--xref-buffer-mode-map): Add `r' binding.
* lisp/progmodes/xref.el (xref-match-bounds): New generic function.
(xref-file-location): Add reader for the column slot.
(xref-match-item): New class.
(xref-match-bounds): A method implementation for it.
(xref-make-match): New constructor function.
(xref--current-item): New private variable.
(xref-pulse-momentarily): Use it.
(xref--pop-to-location): Change the first argument to an xref
item, instead of location, bind xref--current-item.
Update all callers.
(xref-next-line, xref-prev-line, xref--next-error-function)
(xref--mouse-2): Look for the property `xref-item',
instead of `xref-location'.
(xref--item-at-point): Likewise. This function replaces
`xref-location-at-point'. Update all callers.
(xref--insert-xrefs): Add the `xref-item' text property, instead
of `xref-location'.
(xref--collect-match): Use xref-make-match.
* lisp/progmodes/xref.el (xref-after-jump-hook)
(xref-after-return-hook): New hooks.
(xref-pulse-on-jump): Remove, in favor of the above.
(xref-pulse-momentarily): Rename from xref--maybe-pulse.
(xref--pop-to-location, xref--display-position)
(xref-pop-marker-stack): Use the new hooks, as requested in
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.
* src/xdisp.c (Fmove_point_visually): When lines are truncated,
simulate display in a window of infinite width, to allow move_it_*
functions reach positions outside of normal window dimensions.
Remove code that tried to handle a subset of these situations by
manual iteration of buffer text. (Bug#17777)
* 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)
* lisp/international/mule-util.el (bufferpos-to-filepos): New
function.
* etc/NEWS: Mention bufferpos-to-filepos.
