 Wow, I'm shocked that this code wasn't portable to windows. I hate to
 sound like a skeptic ... but I am. Can someone else confirm that this
 change is needed? Or point me to a doc so I can learn another new
 thing today?

Looks like some badness in Python. The windows stuff uses some special
code to do the pipes, and it looks like the APIs aren't matched up.

So the basic concept of the change is good, but I'd break it out into
a local function called _compat_popen() or somesuch. That also
provides a place to document why this is needed. Further, if we end up
with a lot of compat stuff across the bindings, then we can create a
_compat.py (imported as svn._compat) which can hold code for Python
version-compatibility code.
