I experimented a bit, and found that actually what we seem to
need is FindBin::RealBin.  That's the only one of these solutions
that gives the right answer if someone's put a symlink to
unused_oids or duplicate_oids into their PATH --- the other ones
give you the directory containing the symlink.  Now, maybe that
would be an uncommon usage, but it hardly seems out of the question.
