Ok (step 4?), one last patch to show full fidelity between DECO and 
ESCAPE before I rip out DECO stuff.  This also comes with a fix of a 
yet-unnoticed bug: \F escapes were being treated as \f escapes in terms 
of recognising styles (bold, italic, etc.).  However, in the groff 
manual, \F accepts families (Times, Helvetica, etc.) while \f accepts 
styles (duh).  I've actually completely removed the FONTFAMILY notion, 
as we don't really support it (it can be put in later, if necessary, but 
it's unlikely as it can't be reliably displayed across output media).
