If one target for this PEP is script implementors who hadn't thought
about this issue before, it is probably worth mentioning sys.executable
somewhere (a footnote?).

But another issue here (and this speaks against the proposal of not
shipping a /usr/bin/python link) is that it is quite possible to write
a script that will run on either python2 or python3.
