Given the problems I am seeing with tp_compare I'd advise
that you get rid of it for 3.0. The half hearted support is worst
then no support. At least if you remove tp_compare it forces
a porter to implement tp_richcompare.

I've added support already in PyCXX. I'll now implement
tp_richcompare for pysvn and document this in my PyCXX
porting guide.
