Cope with another one of the many kinds of DocBook stupidity:
Instead of just using .br, DocBook sometimes fiddles with the
utterly unportable internal register \n[an-break-flag] that is
only available in the GNU implementation of man(7) and then arms
an input line trap to call the equally unportable internal macro
.an-trap that, in the GNU implementation, inspects that variable;
all the world is GNU, isn't it?
Since naddy@ reports that quite a few ports manuals suffer from
this insanity, let's just translate it to the intended .br.
Et ceterum censeo DocBookem esse delendam.
