description:
It turns out there are more cases where escaping of meta-chars
was not being done properly (too many different code paths inside sh)
so add even more subtests to the case_matching test case to verify
that all (that I can think of for now anyway) get fixed when this
gets cleaned up.   The case_matching test case still fails, but now
6 of its subtests should fail (until sh is corrected ... soon).
