[Groff] problem with preconv and sample_docs.mom

[G. Branden Robinson]

Hi folks,

There is some misbehavior in git HEAD involving preconv and the -k flag
that affects sample_docs.mom but not other documents.

-K ascii works around it for this one document but it seems wrong to
hack mom.am to force that flag for _all_ mom documents, and even more
wrong to special-case it before I understand the problem, which I don't.

Any ideas?

I didn't check the document contents closely; the one with the preconv
problem is a single blank page, and the -K ascii one is 12 pages with a
nice-looking title page.  That was enough to convince me of serious
trouble.

(The "..." is just me censoring my build path; it's not interesting.)
