I'm aiming for self-consistency within the 'PKG-INFO' field names:

 - 'Requires'
 - 'Requires-Python'
 - 'Requires-External'

The 'Obsoletes' and 'Provides' fields also need
distutils-project-oriented versions, so picking a suffix ('-Dist') which
matched for them seemed cleanest.

Add that to the fact that setuptools has no way (yet) to spell
'provides' or 'obsoletes', and it seemed to me clearer to just make
setuptools current argument an alias for the "consistent" version to be
landed in distutils.
