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.
In particular, to prevent scrolling in a window lacking a left fringe.
Instead, a visible arrow "=>" is inserted before column zero. This fixes
bug #36832.
* lisp/progmodes/compile.el (compilation-context-lines): Add the new value t.
(compilation-set-window): Amend to handle compilation-context-lines being t.
(overlay-arrow-overlay): New variable holding an overlay with before-string
property "=>".
(compilation-set-overlay-arrow): New function which manipulates
overlay-arrow-overlay.
(compilation-goto-locus, compilation-find-file): In addition to calling
compilation-set-window, also call compilation-set-overlay-arrow.
* doc/emacs/building.texi (Compilation Mode): Document the new value t which
compilation-context-lines can take.
* etc/NEWS: Add an entry for this change.
* doc/emacs/maintaining.texi (Log Buffer):
* etc/NEWS: Replace log-edit-generate-changelog (an old name which was
changed during editing) to log-edit-generate-changelog-from-diff.
* doc/emacs/misc.texi (Network Security): Start working on
updating the NSM bits, but it's unclear how much of the new stuff
to document.
* lisp/net/nsm.el: Rename all nsm-tls-check-* functions to
nsm-protocol-check--* to bring them back into line with the
documentation.
(network-security-protocol-checks): Renamed back again from
`nsm-tls-checks', as this variable is documented and can't just go
away.
* doc/misc/info.texi (Help-Q): Info now uses `quit-window'.
* lisp/info.el (info-standalone): Adjust doc string.
(Info-exit): Made into obsolete alias.
(Info-mode-map): Bind "q" to `quit-window'.
(Info-mode-menu): Adjust.
(info-tool-bar-map): Ditto.
(Info-mode): Adjust doc string.
(Info-mode): If Info is standalone, kill Emacs on "q".
* doc/misc/emacs-mime.texi (time-date):
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.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode): Accept
a BODY parameter.
* doc/lispref/modes.texi (Defining Minor Modes): Document new
parameter.
* etc/NEWS: Announce it.
* lisp/simple.el (read--expression): Move eldoc-mode setup to...
* lisp/emacs-lisp/eldoc.el (eldoc--eval-expression-setup): ... here,
new function.
(global-eldoc-mode): Add or remove it to
eval-expression-minibuffer-setup-hook when enabling or disabling
global-eldoc-mode. This enables eldoc in the minibuffer (solving
Bug#27202), only when global-eldoc-mode is enabled.
Also, improve the doc to match current behavior.
* doc/lispref/os.texi (Time Conversion): Document that
time-convert signals an error for infinite or NaN args,
and that (time-convert TIME t) is exact otherwise.
Mention float-time as an alternative to time-convert.
(Time Calculations): Document that time-add and time-subtract
are exact and do not decrease HZ below the minimum of their args.
* src/timefns.c (decode_float_time): Don’t signal an error for
floating-point arguments whose base-FLT_RADIX exponent is not less
than DBL_MANT_DIG. Instead, convert them to (TICKS . 1) values.
Use two (instead of three) integer exponent comparisons in the
typical case.
* test/src/timefns-tests.el (time-arith-tests):
Add more floating-point tests, including some tests
that the old code fails.
* doc/lispref/windows.texi (Quitting Windows): Mention in.
* lisp/window.el (quit-restore-window): Run the new
`quit-window-hook' before doing anything else (bug#9867).
(quit-window): Note that the hook will be run in the doc string.
* lisp/window.el (quit-window-hook): New variable.
* doc/lispref/processes.texi (Asynchronous Processes): Note that input
may read when sending data as well.
(Output from Processes): Note that functions which send data may also
trigger reading from processes.
(Input to Processes, Filter Functions): Note that filter functions may
be called recursively.
* doc/lispref/frames.texi (Frame Size): Document it.
* src/frame.c (Fset_frame_height):
(Fset_frame_width): Make into commands that use the numeric prefix
to set height/width (bug#9970).
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) ...) ...)’.
* doc/lispref/os.texi, doc/misc/emacs-mime.texi, etc/NEWS:

* test/src/timefns-tests.el (format-time-string-with-zone)
(encode-time-dst-numeric-zone):
Revert recent changes that added a SUBSECS member to

the `next-multiframe-window' command here (which is otherwise not
documented in the manual) (bug#12431).
* doc/lispref/commands.texi (Reading One Event): Mention that ""
has the same effect as nil as a prompt.
* src/lread.c (Fread_event, Fread_char_exclusive, Fread_char):
Mention what happens when PROMPT is nil/"" in the doc string
(bug#15012).
