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.

An efficient reuse of "--" ;-)

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