I fixed typos in the commit message, which Alvaro pointed out off-list,
and revised the message a little bit. Also, I reread the patch and
noticed that the latest version includes now-unnecessary regression test
cases; those were added to the previous version
(refuse-pwj-when-wrvs-involved-2.patch in [1]) to check that
apply_scanjoin_target_to_paths() and create_ordinary_grouping_paths()
work for cases where whole-row Vars are involved, because I modified
those functions, but the latest version doesn't touch those functions
anymore, so those test cases seems unnecessary. So I removed those (no
other changes), and committed the patch.

Best regards,
Etsuro Fujita
