I don't care for "NO ACTION" either.  However, the prior discussion had
to do with what to echo in the case that you are saying COMMIT in a
failed transaction.  I don't think anyone thought about this particular
corner case, viz COMMIT outside any transaction.  I think you could make
a reasonable argument that the tag should remain COMMIT for this case,
since we do not consider it an error.

On the other hand, it's also a pretty minor issue, and if it turns out
to require a lot of code rejiggering to make it do that, I'd not think
it worthwhile.
