tests: demonstrate broken manifest generation with the pure module This will be fixed next. But I don't fully understand how 'b.txt' is actually removed properly in the second test, given what's broken. Also, I'm not sure why 'bb.txt' is flagged as not being in the manifest, when it clearly appears to be.

import pkgutil
__path__ = pkgutil.extend_path(__path__, __name__)
