Minimum supported Python version has been 2.4, though we're bumping that up to 2.5 for the next release.

I should have thought to check the Python version support when we added `-x`; I guess I just assumed that since I'd never heard of the `-x` flag it was probably one of those things that had been around since early days. So I guess we need a CPython version check in addition to the `is_jython` and `is_pypy` checks. (I don't feel the need for it to be an `is_cpython` check; if IronPython supports it that indicates it isn't only CPython, and I doubt there's any solid reason it isn't supported (yet?) in Jython or Pypy, probably just a low priority item that nobody has asked for.

Any thoughts on whether we should break long paths or Unicode paths for Pythons without `-x`? I'm inclined to break Unicode paths, but not due to a deeply-considered evaluation of which is more likely, just because it keeps the code simpler if we always run `python ...`.
