The big problem is that implementations don't do that :-( AFAIK, none of
distlib, pip or wheel itself do anything with script wrappers except
rewrite #! lines (which is the other, much easier, item in that section).
At the moment, bdist_wheel just puts the exe wrappers generated from the
source into the wheel itself, which again is probably wrong in the context
what the PEP suggests.
As I said in my other email, I think this is subtle enough that we need a
stdlib implementation to stop people making mistakes like this. It's
certainly not fair to expect a mostly-Unix development team to get this
sort of Windows arcana right without some help.
