Thanks! I'll see if I can work this in soon.

If you're constructing a TestProgram, you can pass in a list of plugin
instances. If I recall correctly, you have to pass in every plugin
that you might want to use, even if they're builtin (I suppose the
given list replaces the internal plugin list somewhere, I haven't
traced it). So if you leave the doctest plugin out of this list, for
example, the "--with-doctest" will cause an error. (This is all from
memory, though, so take it with a grain of salt)

I'd be surprised if it did; I'll have a look.

Certainly, thanks for doing it!
