* 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 ' $' <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 was the outcome of this action?

troff:<stdin>:214: warning: [page 2, 8.4i]: cannot break line

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

troff:<stdin>:204: warning [page 2, line 54]: cannot break line
troff:<stdin>:209: warning [page 2, line 57]: cannot break line
troff:<stdin>:214: warning [page 2, line 60]: cannot break line


   * What outcome did you expect instead?

     No output (no warnings).

Who is actually creating this man page?  Debian or upstream?

Is the generating software out of date?
