More than that. Add pythonX.X. You may want to run Python3.5 and not

It would work better and be cleaner, but is unlikely to happen. 1) is
simpler and have a chance to happen.

Yeah, if 1) happens, we should promote -m for pip.

Agreed. But if an existing python exist in the path, there should be a

Breaking compat ? Not sure people will accept.
