This was an ill-advised optimization attempt in glob.  I revert the
patch and pushed the change(*), so this will be fixed in Cygwin 3.5.2.

For the time being, you can also test this by installing the just
building Cygwin test release 3.6.0-0.85.g89afbb8d8af2, which should
be available in an hour or two.


Thanks,
