Is there a way to get SWIG to do this that isn't totally abusive? I
figured out one way, but it is so overwhelmingly hacky that I'm too
embarrassed to mention it in public. :)

Hardcoding it seems like the simplest approach. It is only three
functions, after all.

And speaking of svn_client_diff, is there a way to construct something
in python that maps to an apr_file_t? Or do we also need to put that on
the to-do list?

Yeah, it looks like thunks should be pretty doable using a
multiple-argument typemap.

I can at least help out with the trivial bits. Attached are two (very
small) patches: the first one fixes the crash in the svn_client_proplist
wrapper, and the second allows the xml_src and xml_dst arguments to be
None.

Thanks,
