This seems like an unusual case, since the package in question appears
to be a build-time tool. So, it would make sense to have things like
python-pytest available during python-pytest-pep8's run-time.

If we have a use case for python-pytest-pep8, it could be worthwhile to
see if it will work without propagating these anyways; I've noticed some
Python packages have a way to link to non-propagated-inputs.
