commit 8dfba7c051d1b91192516316671147ad22ac0207

groff_mm(7): Fix content and style nits.
* "mm" is a groff "contrib" project, meaning that it is not part of the
"official" package, and should not be labelled as "GNU". This
observation may split hairs, as groff has distributed this mm package
for over 30 years. Nevertheless, we strive for the best kind of
correctness.
* Similarly, qualify extensions as "groff mm" rather than "GNU", or
without qualifier where context is clear.
* Protect a literal from hyphenation.
