Yes, I think that is a reasonable way to go.

Keep in mind that you might not even have a terminal at all (e.g., tests
run from a cron job), so redirecting /dev/tty won't help there. It is
easy enough to fake, as I posted in the other thread, so I think that is
probably simplest (unless we go with the "it only works under
--verbose" scheme).
