Could $curdir have glob wildcard to throw this part of the logic off? It is OK to have limitations like "you cannot have a glob characters in your path to submodule working tree" (at least until we start rewriting these in C or Perl or Python), but we need to be aware of them.

It somewhat looks strange to start with "<<-EOF" and then not to indent the body nor EOF.
