The function `fill-region-as-paragraph' leaves a temporal marker which
isn't cleared in the buffer.

Here is the structure of `fill-region-as-paragraph':
----------------------------------------------------------------------
(defun fill-region-as-paragraph (from to &optional justify
				      nosqueeze squeeze-after)
[...]
    (setq to (copy-marker (point) t))
[...]
  (if (not (> to (point)))
      nil ;; There is no paragraph, only whitespace: exit now.
[...]
      (goto-char to)
      (unless (eobp) (forward-char 1))
      ;; Return the fill-prefix we used
      fill-prefix)))
----------------------------------------------------------------------
With this code, temporal marker bound to local variable `to' is left in
the buffer. According to elisp reference `(elisp) Overview of Markers',
it is recommended to clear such stale marker with suitable `(set-marker
MARKER nil)':
,----
|    Insertion and deletion in a buffer must check all the markers and
| relocate them if necessary.  This slows processing in a buffer with a
| large number of markers.  For this reason, it is a good idea to make a
| marker point nowhere if you are sure you don’t need it any more.
`----
I'd propose to apply the attached patch to accomplish that.

Regards,
Ikumi Keita

Looks good to me, so I've applied it to Emacs 29.

This change was small enough to apply without assigning copyright to the
FSF, but for future patches you want to submit, it might make sense to
get the paperwork started now, so that subsequent patches can be applied
speedily. Would you be willing to sign such paperwork?

I've already signed copyright assignment with my former email address
ikumi@revery.net, but it might be for AUCTeX only (sorry, my memory
isn't clear enough with respect to its coverage.) If so, I'm willing to
sign for other projects including Emacs for FSF.

Regards,
Ikumi Keita

Yup, I see the assignment for AUCTEX, but not for Emacs as a whole.

Here's the form to get started with the Emacs assignment process:

Please email the following information to assign@gnu.org, and we
will send you the assignment form for your past and future changes.

Please use your full legal name (in ASCII characters) as the subject
line of the message.

REQUEST: SEND FORM FOR PAST AND FUTURE CHANGES

[What is the name of the program or package you're contributing to?]
Emacs

[Did you copy any files or text written by someone else in these changes?
Even if that material is free software, we need to know about it.]

[Do you have an employer who might have a basis to claim to own
your changes?  Do you attend a school which might make such a claim?]

[For the copyright registration, what country are you a citizen of?]

[What year were you born?]

[Please write your email address here.]

[Please write your postal address here.]
