I tested the return codes of those system calls, but that wasn't
directly helpful because the error is that 'grep' succeeds when
it should fail.

Results are as expected if I change the unit test so that it
invokes an msw-native port of 'grep' by absolute pathname.
Occasional failures arise when invoking Cygwin's 'grep' through
CreateProcess(), but perhaps that is not expected to be robust;
I won't worry about it, because our end users aren't invoking
any Cygwin programs through lmi.
