Calling glob.glob(pattern, recursive=True), where pattern contains two or more **/ segments, can yield the same paths multiple times:

>>> import glob
>>> len(glob.glob('**/**', recursive=True))
314206
>>> len(set(glob.glob('**/**', recursive=True)))
44849

    Reasonably minor bug I think as these patterns are pretty rare. A note in the docs might be the best solution.
