Ingo, if you and Jason think this is worth the effort (and correct), 
then by all means.  HOWEVER.  `Bk' is a turd that should be flushed: it 
gives the author unnecessary control over output.  This is wrong.

What we should do is ignore `Bk' and follow an easy algorithm for 
SYNOPSIS mode regarding breaking between children.  This, I think, is 
easier for us and manual writers alike.

Is `Bk' used often outside of this where .nr nS 1 is otherwise 
unacceptable (like those OpenBSD .9 manuals)?
