Your comment made me double-check whether we ought to be separating the
two in any way. Because my statement earlier in the thread that the
--verbose output goes to stdout is not _entirely_ true. It goes to
stdout and stderr, as written by the various programs in the tests.

So:

  ./t0000-whatever.sh -v | less

isn't quite sufficient. You really do want "2>&1" in there to catch
everything.

But for the case of "--tee", we already do so, in order to make sure it
all goes to the logfile. And since this option always implies "--tee",
it is correct here to send "3" and "4" to the same place.

So the patch is correct. But when I said earlier that people might be
annoyed if we just sent --verbose output to stderr, that probably isn't
true. We could perhaps make:

  prove t0000-whatever.sh :: -v

"just work" by sending all of the verbose output to stderr. I don't
think it really matters, though. Nobody is doing that, because it's
pointless without "--tee".
