That's why I didn't consider it robust enough :)

I had been trying this which seems to handle both:
grep -E " {2,6}-.*[^.]  [A-Z][a-z]" *.c

Searching man files allows us to take advantage of the extra
formatting to catch all cases (even though there currently any
extra found by this):
grep -E '^\\fB\\-' -A1 man/*.1 | grep '\.1.[A-Z][a-z]'

I'll play around with it some more and come up with something.

Pádraig.
