* lisp/emacs-lisp/cl-seq.el: (cl-reduce): Clarify treatment of

`list-tags' doc (bug#37611).

(tags--get-current-buffer-name-in-tags-file): Default FILE to the
current buffer for list-tags.
* lisp/emacs-lisp/seq.el (seq-find): Autoload.

entries come from so that we can later distinguish between user
values and system values (bug#36771).
(mailcap-parse-mailcap): Take a source parameter.
(mailcap-possible-viewers): No need to sort wildcards/exact
matches; these are later sorted anyway.

is not in an editable field.
(widget-complete): And here say there are no completions available
(bug#11562).

(eieio--full-class-object): New function, to replace it.
(eieio-oref, eieio--class-precedence-list):
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-convert-list-to-object):
Use it instead of eieio-class-un-autoload.
* lisp/emacs-lisp/eieio.el (eieio-class-parents, child-of-class-p):
Load the class if needed.

should trigger redisplay of the current buffer.

Problem reported privately for FreeBSD 12 by Ashish Shukla.

acl_get_file fails, to port to FreeBSD 12 and other non-GNU
platforms.
This for now doesn't work on GPM.

items more efficient.

CHARPOS.

(iso8601--week-date-match, iso8601--ordinal-date-match)
(iso8601-parse-date):
Don’t bother to separate the year’s sign from the year,
as that distinction is not needed: ISO 8601 uses
astronomical year numbering with a year zero, which
is what the Emacs time functions use, so there’s no
need to treat nonpositive years specially.
(iso8601--adjust-year): Remove; no longer needed
since callers can just use string-to-number.

Adjust test case to match fixed behavior.
* doc/emacs/calendar.texi (Calendar Systems)

as offset relative to the current tab.
(tab-bar-switch-to-tab): New command.
(tab-bar-new-tab): Simplify by using cl-pushnew.

becomes garbaged inside the call to update_frame, and redraw
the frame in that case. (Bug#37579)
* lisp/image-mode.el (image-set-window-vscroll): Interpret the
argument VSCROLL value in pixel units.
(image-mode-reapply-winprops): Interpret the 'vscroll'
property value in pixel units.
(image-next-line): Scroll the image with pixel resolution.
(image-eob): Set the image vscroll in pixels. (Bug#37578)
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--mode-docstring):
When using `easy-mmode--arg-docstring' to auto-generate a
docstring, refill it up to `emacs-lisp-docstring-fill-column'.

Gnus summary mode without actually booting Gnus might end up in this
situation. See bug#36903
