* 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 "groff -e ' $' -e '\\~$' <file>" to find obvious 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 outcome did you expect instead?

     No output (no warnings).

N.B.

  The man page contains an 8-bit character, so the mailer uses base64
encoding for that attachment.

  General remarks and further material, if a diff-file exist, are in the
