Yes, it fixes the issue. I wrote "should" because I was a bit in a
hurry and hadn't put much thought into whether it's the best way to
fix that issue (or if there even is an issue that should be fixed).
Now that I thought a bit more about it, I think it's a decent fix for
the issue. There is still the possibility that a custom __repr__
method calls `object.__str__`, but that will either raise a
RuntimeError at some point (due to stack exhaustion; if the method is
a Python method) or it's a case of "well, don't do that" (if the
method is implemented in C).

I updated the patch and put a test into test_class which seemed like a
good place for it to me. Also, I did the patch against the 3.1 branch
this time, so it can be forward-ported.
