I'm okay with this, but I think Tom had some valid reasons for having
Python scripts that don't have a certain extension.

Fine with me.

I think there is already a way to do that: the `python' command. I
think the `source' proposal was intended to treat Python scripts more
similar to GDB scripts, and I generally agree with that idea,
i.e. that we should have a single command that sources scripts.
