I wouldn't swear to this, but the problem probably results from a
troff requirement/bug.  Have you mounted the font CW in one of the
available font positions, with `.fp x CW'? Try that.  You could
also change the DESC file.

The reason: troff reads its input until it reaches a word that can
no longer be fit into the output line.  Then it justifies the line
and lays it on the page.  The justification is the last thing it does.
It can't compute the width of a CW character at that point unless
the font is mounted.

This may be stated imprecisely.  I'm trying to recall something I read
once about troff and can't think of right now.   

A recent book from Hayden, UN*X Text Processing, by Dale Dougherty
and Tim O'Reilly, is the best, most comprehensive thing I've seen
on n/troff.  The answer is probably rattling around somewhere among
its 650+ pages.
