[Groff] Another book to add to troff.org

[Larry Kollar]

Hi Ralph,
One of my co-workers was a co-author of "Preparing Documents with Unix" and I 
don't see it in the "Books about troff" list. The following Amazon link has a 
shot of the book cover to borrow, too.

Good to know — they could just dump all my work into her lap and she'd know 
what to do with it. :-D
