* What led up to the situation?

     Checking for defects with a new version

test-[g|n]roff -mandoc -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=10 -ww -z < "man page"

  [Use

grep -n -e ' $' -e '\\~$' -e ' \\f.$' -e ' \\"' <file>

  to find (most) trailing spaces.]

  ["test-groff" is a script in the repository for "groff"; is not shipped]
(local copy and "troff" slightly changed by me).

  [The fate of "test-nroff" was decided in groff bug #55941.]

   * What was the outcome of this action?

Output from "test-nroff  -mandoc -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=10 -ww -z ":

an.tmac:<stdin>:5: style: .TH missing third argument; consider document modification date in ISO 8601 format (YYYY-MM-DD)
troff:<stdin>:16: warning [page 1, line 9]: cannot break line; overset by 31n
troff:<stdin>:17: warning [page 1, line 10]: cannot break line; overset by 12n
troff:<stdin>:18: warning [page 1, line 11]: cannot break line; overset by 12n
troff:<stdin>:19: warning [page 1, line 12]: cannot break line; overset by 13n
troff:<stdin>:19: warning [page 1, line 13]: cannot break line; overset by 17n

   * What outcome did you expect instead?

     No output (no warnings).

Hi!

Thanks for your attention to detail. I have committed your suggested
chanegs to git, targeted for master after the trixie release. Since the
manual pages are translated, this will not go into trixie.
