When "downloading" a directory given by file-system path or ``file:`` URL and
using a download cache at the same time, the cached directory wasn't handled
correctly. Consequently, the cache was defeated and an attempt to cache the
directory a second time broke. This is how it should work:
>>> download = Download(cache=cache)
>>> dirpath = join(server_data, 'some_directory')
>>> mkdir(dirpath)
>>> dest, _ = download(dirpath)
If we now modify the source tree, the second download will produce the
original one from the cache:
>>> mkdir(join(dirpath, 'foo'))
>>> ls(dirpath)
d foo
>>> dest, _ = download(dirpath)
>>> ls(dest)
