on an error when isearch-wrap-pause is no/no-ding.

Fix the bytecode incompatibility due to the change to 'narrow-to-region'.

* src/editfns.c (narrow_to_region_internal): New function, which
contains the body previously in 'Fnarrow_to_region' but accepts
a third argument.
(Fnarrow_to_region): Use the new function. Update the docstring.
(Fwiden): Update the docstring.

'Fnarrow_to_region'.

Fix loaddefs quirk w.r.t. pinyin-convert

* lisp/international/titdic-cnv.el (pinyin-convert): Use
`generate-lisp-file' for the file.  This avoids having it scanned

Fix time comparison in primitive-undo

* lisp/simple.el (primitive-undo): Fix time comparison.
The old code was a circa-2013 mistranslation of what used to be in
src/undo.c’s Fprimitive_undo.

Use list-form timestamps in .nnmh-articles

* lisp/gnus/nnmh.el (nnmh-update-gnus-unreads): Store list form
timestamps into .nnmh-articles, even if current-time-list is nil.
That way, older Emacs versions can read them.

This is more robust since timestamps can have multiple forms.

timestamps for equality.

Simplify a few timestamps

* lisp/calendar/time-date.el (safe-date-to-time):
* lisp/calendar/timeclock.el (timeclock-generate-report):
* lisp/epg.el (epg--start):

* lisp/vc/ediff-util.el (ediff-command-begin-time)
(ediff-calc-command-time, ediff-profile):
Prefer an integer like 0 to a timestamp list like (0 0)
where either will do.

Omit some (current-time) calls

* lisp/emacs-lisp/ert.el (ert-write-junit-test-summary-report):
* lisp/emacs-lisp/shortdoc.el (file):
* lisp/find-lisp.el (find-lisp-find-dired-insert-file):
* lisp/progmodes/hideif.el (hide-ifdefs):
* lisp/tar-mode.el (tar-subfile-save-buffer):
Prefer nil or omitted arg to (current-time) where this is better
or more-efficient.

* lisp/vc/vc.el: Remove stray comment hyphen.

Fix "cons up a storm" issue in type-break

* lisp/type-break.el (type-break-time-last-command)
(type-break-mode, type-break, type-break-check)
(type-break-time-sum, type-break-keystroke-reset):
Use integer timestamps; that’s good enough for this module.

Fix year-285428751 bug in hanoi-unix-64

* lisp/play/hanoi.el (hanoi-move-period, hanoi, hanoi-unix)
(hanoi-unix-64): Use integers, not floating point, to avoid
rounding errors for timestamps greater than 2**53.

* src/timefns.c (Ffloat_time): Fix doc string.

Improve time-equal-p etc. performance

* src/timefns.c (time_cmp): Return EMACS_INT, not int; no need to
change callers.  Compare (X . Z) to (Y . Z) quickly if X and Y are
fixnums.

Improve float-time etc. performance

* src/timefns.c (decode_float_time): Assume T is finite.
All callers changed.
(decode_time_components): Assume FORM is not TIMEFORM_FLOAT.
All callers changed.
(decode_lisp_time): If the specified time is a float,
signal an error if it is not finite.
(Ffloat_time): If the specified time is a float,
simply return it.

Make time arithmetic more like comparison

Since time comparison says X == X, have time arithmetic behave
similarly for X - X.  This should also be a bit faster due to not
having to test for floats and NaNs.
* src/timefns.c (time_arith, time_cmp):
Simplify by not worrying about NaNs, which are not time values.
(time_arith): Simplify by not worrying about subtracting nil from
nil; the caller now handles this.
(Ftime_subtract): Handle subtracting X from X specially.

Fix get-internal-runtime precision

* src/sysdep.c (make_lisp_s_us): Also define if HAVE_GETRUSAGE.
(Fget_internal_run_time): Don’t generate more precision than the
underlying primitives.

(time-equal-p nil X) returns nil

* src/timefns.c (Ftime_equal_p): nil compares unequal to non-nil.
