Turns out you cc'ed the right persons :)

Then you would not be able to use git-svn with your setup!

Having svn and its bindings at different versions is perfectly fine for
git-svn: it uses and cares about the bindings only (and adjusts
according to the binding's version).

It's only the test suite which cares, because it tries to make sure that
"svn" and "git-svn" behave as similar as possible.

We should probably check in the test suite before triggering false
alarms, I'll look into that.
