Ingo,

I'm fine with this.  Is there some place in {mdoc,man}(7) where we 
should be noting this?  It seems that a few words regarding hyphenation 
would be useful, to wit, noting that hyphens will not break within a 
macro in mdoc(7), but will in a regular text context, and the conditions 
for such breakage.

Thoughts?
