This incorporates:
2019-08-25 intprops.h, verify.h: port better to clang
2019-08-21 New strip-trailing-space option for srclist-update
* .gitattributes: Remove doc/misc/texinfo.tex special case,
which is no longer needed now that Gnulib trims blank-at-eol.
* build-aux/install-sh, doc/misc/texinfo.tex, lib/intprops.h:
* lib/regex_internal.c, lib/verify.h: Copy from Gnulib.
Fit in better with the XDG conventions.
Something like this was suggested in 2008 (Bug#583)
and the XDG conventions seem to have settled down by now.
* doc/emacs/custom.texi (Init File, Init Syntax, Find Init):
* doc/lispref/files.texi (Standard File Names):
* doc/lispref/os.texi (Init File):
* doc/misc/url.texi (Customization):
* etc/NEWS:
Adjust accordingly.
* lisp/startup.el (startup--load-user-init-file):
If init-file-name is nil, do not load from it; instead
just use the alt-file.
(find-init-path): Remove; no longer used.
(command-line): Don't check twice for XDG.
Look at XDG_CONFIG_HOME instead of assuming it's ~/.config.
Prefer XDG configuration if it exists; the user can disable
this by setting XDG_CONFIG_HOME to some other place.
* lisp/subr.el (user-emacs-directory):
Prefer XDG configuration if it exists.
* doc/misc/info.texi (Help-Int): Using tool-bar to navigate history.
* lisp/info.el (Info-history-menu): New function.
(Info-history-back-menu, Info-history-forward-menu): New commands.
(Info-mode-map): Bind Info-history-back-menu and
Info-history-forward-menu to tool-bar on C-key.
* doc/misc/info.texi (Help-Q): Info now uses `quit-window'.
* lisp/info.el (info-standalone): Adjust doc string.

(Info-mode-menu): Adjust.

Adjust example to match new behavior.
* etc/NEWS: Mention this.
* lisp/calendar/time-date.el (decoded-time-add)
(decoded-time--alter-second):
Don’t lose underestimate precision of seconds component.
* src/bignum.c (mpz): Grow by 1.
* src/timefns.c (trillion_factor): New function.
(timeform_sub_ps_p): Remove.
(time_arith): Avoid unnecessarily-large hz, by reducing the hz
to a value no worse than the worse hz of the two arguments.
The result is always exact unless an error is signaled.
* test/src/timefns-tests.el (timefns-tests--decode-time):
New function.
(format-time-string-with-zone): Test (decode-time LOOK ZONE t)
resolution as well as its numeric value.
Instead of appending a subseconds member to the result of
‘decode-time’, this keeps the format unchanged unless you give
a new optional argument to ‘decode-time’. Also, the augmented
format now puts the subsecond info in the SECONDS element, so
the total number of elements is unchanged; this is more
compatible with code that expects the traditional 9 elements,
such as ‘(pcase decoded-time (`(,SEC ,MIN ,HOUR ,DAY ,MON
,YEAR ,DOW ,DST ,ZONE) ...) ...)’.

Rewrite in a way that I understand, and that actually seems to work.
(math-absolute-from-julian-dt): Use Julian, not Gregorian, leap year
rules for counting days within a year.
(math-julian-date-beginning, math-julian-date-beginning-int):
Change constants to be consistent with their doc strings and the code:
use Rata Die epoch at Dec 31, 1 BC Gregorian proleptic, not Julian.
* doc/misc/calc.texi (Date Forms): Correct difference between Julian
Day and Rata Die.
* test/lisp/calc/calc-tests.el (calc-test-calendar): New test.
The list that decode-time returns now contains an extra
trailing component that counts the subseconds part of the
original timestamp (Bug#36549).

This replaces the awkward reuse of encode-time to both convert
calendrical timestamps to Lisp timestamps, and to convert Lisp
timestamps to other forms. Now, encode-time does just the
former and the new function does just the latter.

Do not attempt to encode time values; just encode
decoded (calendrical) times.
Unless CURRENT_TIME_LIST, just return VALUE since HZ is 1.
(Ftime_convert): New function, which does the time value
conversion that bleeding-edge encode-time formerly did.
Return TIME if it is easy to see that it is already
of the correct form.

* test/src/timefns-tests.el (decode-then-encode-time):

(browse-url-botton-regexp): New variable.
(browse-url-button-map): New keymap.
(browse-url-button): New face.
(browse-url-add-buttons): New function to add clickable browse-url
buttons to almost any buffer.

(shr-browse-url): Adjust usage.
Updating group splits requires the gnus-newsrc-hashtb to be
initialized. Previously this failed silently, now it errors.
* lisp/gnus/gnus-mlspl.el (gnus-group-split-setup): Don't call the
update when loading the user's init file, that's too early. Use
appropriate hooks depending on AUTO-UPDATE.
* doc/misc/gnus.texi (Group Mail Splitting): Change mention in docs.
* doc/misc/smtpmail.texi (Authentication): Document it.

* lisp/gnus/gnus-sum.el (gnus-shorten-url): New function.
(gnus-summary-browse-url): Change function to make `C-u' use the
external browser (as Gnus does when you hit URLs manually). Don't
use an initial input.
* doc/misc/efaq.texi (No Escape key):
* doc/emacs/msdos-xtra.texi (MS-DOS Keyboard): Change back to
function-key-map from local-function-key-map, because these

circumstances you may still want to use function-key-map.

local-function-key-map instead of function-key-map, since the
latter isn't supposed to be changed (bug#27490).
* lisp/gnus/gnus-art.el (article-make-date-combine-with-lapsed) factor
code out into new function, used for providing both combined-lapsed
and combined-local-lapsed.
* doc/misc/gnus.texi (Fancy Mail Splitting): Mention it.
* lisp/gnus/nnmail.el (nnmail-debug-splitting): New variable.
* lisp/gnus/nnmail.el (nnmail-log-split): New function.

gnus-read-ephemeral-emacs-bug-group for multiple bug
IDs (bug#11961).
* lisp/gnus/gnus-group.el (gnus-bug-group-download-format-alist):
Use HTTPS for Debian's bug tracker.
(gnus-group--read-bug-ids): New function for reading multiple bug
IDs in the minibuffer. Improves on previous brittle approach of
word-at-point -> read-string -> string-to-number by a) defaulting to
the more accurate bug-reference-bug-regexp or number-at-point
without using the intrusive INITIAL-INPUT argument, and b) not
attempting to parse bug IDs.
(gnus-read-ephemeral-bug-group): Use it. Extend docstring and
commentary. Fix handling of multiple bug IDs as either numbers or
strings. Hoist some string consing out of inner loop. Delete
temporary file even on error. Throw more informative error when
url-insert-file-contents successfully returns an error (bug#36433).
(gnus-read-ephemeral-debian-bug-group): Use gnus-group--read-bug-ids
and fix docstring for multiple bug IDs. Accept optional WINDOW-CONF
like other ephemeral bug group commands.
(gnus-read-ephemeral-emacs-bug-group): Use gnus-group--read-bug-ids
and fix string/numeric ID conversions. Try loading debbugs-gnu
before testing for debbugs-gnu-summary-mode (bug#36433).
