To me, having 'py' on Unix would be a good thing(tm).  If we have
that then I suppose we will encourage people to prefer it over
'python', 'python3', and 'python2'.  At that point, where 'python'
points would be less of an issue.

I'm not opposed to making 'python' configurable or eventually
pointing it to python3.  However, if we do go with 'py' as the
preferred command in the future, it seems to be some pain for little
gain.  If the OS already allows it to be re-directed, maybe that's
good enough.
