Starting from 'emacs -Q':

1. M-x woman

2. Select groff, then groff.1

What I expected: a buffer containing a nicely formatted man page for

groff.

What I got: a fundamental-mode buffer containing a garbled version of

the nroff src of the man page.

Commentary:

1.  the page src has a definition (.de ...) of a font \f[CR]

which does get parsed correctly.  Then WoMan complains that CR is an

unknown font and eventually seems to give up on formatting.

2.  I get this behaviour with some other man pages but chose this one as

a typical example.

Thanks!
