I had expected this to me marked for 'master'.

Has this simply been overlooked, or do you have reservations about
applying this patch? If so, then I need to find another solution
very quickly [1] (before v1.8.4).  At this time, despite passing the
test suite [2], the cygwin build is still very much broken.

ATB,

[1] I do have another patch, patch #0 actually, which I said I didn't
want applied! :-P

[2] I ran the test suite on v1.8.4-rc0 + 1 patch, like so:

$ GIT_SKIP_TESTS='t0061.3' make test >test-outp16 2>&1

$ tail -17 test-outp16
[22:33:53] t9902-completion.sh ................................ ok    13650 ms
[22:34:26] t9903-bash-prompt.sh ............................... ok    33468 ms
[22:34:26]
All tests successful.

This was over 30 minutes faster than the last full test suite run, but it also
ran more tests (420 test files ran faster and 16 new test files were run).
I've *never* had the test suite run faster before! (I'm not going to celebrate
too much; it still took  9581s = 2h39m41s).
