tests/testlib/pythonpath.sh exists to solve exactly this, and it does it
by simply prepending $TESTDIR/.. to $PATH. It unfortunately looks like
doesn't do its job on Windows very well. But the proper fix to the
issue this patch addresses would be to modify pythonpath.sh for
Windows (or rewriting it in Python to be more cross-platform?).
