Applied after rather extensive editorialization.  Aside from the points
we already discussed, I redid the logic in _bt_check_unique ... it
didn't look right to me, and I also felt that we need a cross-check
to verify that the original tuple's index entry gets found in the
UNIQUE_CHECK_EXISTING search.

I'm going to go add the point about better support of bulk updates
to TODO.
