OK, the first for a feature that is not already written in python
(leading into my second claim that python is used only for fringe
commands ;) ).

Though maybe I am wrong that the remote-svn stuff requires python. I
thought it did, but poking around, it looks like it's all C, and just
the "svnrdump_sim" helper is python.

At any rate, I think the point still stands that perl is our main
scripting language. I'd rather keep us to that unless there's a good
reason not to.
