bug#20118: 25.0.50; tramp-test29-vc-registered aborts on Cygwin

[Ken Brown <kbrown@cornell.edu>]

The outward symptom is almost identical to that of Bug#20117, but I
don't know if the present bug is related, because it's been happening
for as long as I can remember; I just never got around to reporting it.

Test tramp-test29-vc-registered aborted with non-local exit
