[Python-porting] Shebang lines for Python 3

OK, so actually Arch was the counterexample given in the other
discussion too.  Does Arch not include a python3 alias?  Is it safe to
say that Arch was really stupid for doing this, as it will break every
single Python 2 script that someone wants to use, so that we can just
ignore it?

And can someone point to relevant distutils documentation on how to do
this?  I don't think that Vladimir's actually set up our setup.py
script yet to handle our Python 3 work.
