test-git-export: add globs the test runner wants on Windows

The only difference for the first two was to add the globs, but the third line
of output on Windows was '..\dir2\copy'.  I'm not sure why 'copy' is output on
Windows instead of '*'.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
