Hasn't been much of a need for that but knock yourself
out if you think something like a ... might be useful.

Look for function "file_match_pattern" if you want
to extend it.

There is a file name matching option "N:" that
does something similar.

Difference is that F: patterns matches do not
use git history by default to find other people
that have submitted patches, N: does.
