Maybe.  Can someone please investigate this further?  In case it is a
bug, I would like to have a small code fragment which shows the bug.

Note that this:

  .de xx
  Hallo!
  ..
  \fB.xx\fP

has been normalized if not in compatibility mode: now it prints `.xx'
in boldface and not `Hallo!'  (as AT&T troff does).  I don't know
whether this is related to the problem.

This is a new warning message which can be suppressed by adding `-W
break'.  Usually, it indicates a serious typographic problem; in most
cases it is a single word filling a whole line which can't be aligned
because it's too long or too short.
