Hrm. Yes, I removed those changes because I want to think more about
that aspect of things.

yeah well, there's a consistency problem. If we remove default for these
we should remove default for all.

The bug I think is in your original patch in fact to just remove those
from .config rather than explicitely set them to "not set".

I'm not going to remove the applied patch to avoid rebasing, it's
harmless to keep it in, please send another one that does the above.

Ben.
