But this is simply an incorrect package definition, surely? The
setup.cfg override is correct, as would be overriding the wheel to be
py27.py3 (with a separate wheel depending on argparse for py26). The
original form specifies a universal wheel, but provides metadata that
isn't correct for a universal wheel...

Maybe it's not as easy as it could be to *do* this, but nevertheless,
it is possible to specify statically the correct metadata.
