Dear Maintainer,

From "/usr/share/doc/debian/bug-reporting.txt.gz":

  Don't file bugs upstream

   If you file a bug in Debian, don't send a copy to the upstream software
   maintainers yourself, as it is possible that the bug exists only in
   Debian. If necessary, the maintainer of the package will forward the
   bug upstream.

-.-

  I do not send reports upstream if I have to get an account there.
The Debian maintainers have one already.

  If I get a negative (or no) response from upstream, I send henceforth
bugs to Debian.

-.-

   * 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=0 -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?
