I'm inclined to think that that's not a fatal objection; it's not like
we haven't felt free to change psql's output format before.  As long as
we don't back-patch this change, it should be no worse than other things
we've done to third-party code without a backwards glance.

It would be good to get rid of this whitespace because (I believe) it is
one of very few reasons for needing to have any trailing whitespace in
git-controlled files.  If we could get to a point where trailing
whitespace in patches could be rejected automatically, it'd eliminate
one small pet peeve.
