Oh, a related, but different bug would be, if getcwd isn't on the system, or
fails, I think "." might be better than "", as we form getcwd '/' argv[0], and
that doesn't make any sense as "" really.  ./a.out seems better than /a.out for
example.  I merely copied the bug from the other code path for uniformity, not
because I thought it was the right value.
