Unexpected pass for t6120-describe.sh on cygwin

I ran the test-suite on the 'pu' branch last night (simply because
that was what I had built at the time!), which resulted in a PASS,
but t6120 was showing a 'TODO passed' for #52.
This is a test introduced by Michael's 'mg/name-rev-tests-with-short-stack'
branch, which uses 'ulimit -s' to try and force a stack overflow.
Unfortunately, 'ulimit -s' seems to have no effect on cygwin. I created
a test program (see below) to eat up the stack and tried running it
with various ulimit values (128, 12, 8), but it always seg-faulted
at the same stack-frame. (after using approx 2MB stack space).
So, it looks like all ULIMIT_STACK_SIZE tests need to be disabled
on cygwin. I also wonder about the ULIMIT_FILE_DESCRIPTORS tests,
but haven't looked into it.
Given that 'ulimit' is a bash built-in, this may also be a problem
on MinGW and Git-For-Windows, but I can't test on those platforms.
Unfortunately, I can't spend more time on git today, hence this
heads up! ;-)
