Pasky wants to have one of the files in ~/.git-something if I
understand correctly.  I did not want to remove --exclude-from
for that reason.

And I wanted for people's script and existing ignore files to
continue to work.

Yes, but that means you need to always prepend the current
directory being looked at to get the original behaviour.  The
way it was originally done without FNM_PATHNAME was far easier
to read, at least for me.
