I ran the test set with shared build (ra_local, ra_svn, ra_dav) and here
is the report:

ra_local: all test passed
ra_svn: 1 failed, export_tests.py 6: export with keyword translation
ra_dav: 1 failed, export_tests.py 6: export with keyword translation

Without the patch, the merge tests will fail.

Here is the used patch, I had to apply Bryan's patch by hand, because
it was out of date. So the included patch is the Brian's patch, and
hopefully it is exactly same as original (it should be).

BR, Jani
