I think this is OK, though...

I think you can just spell this:

  cat >&4 ...

(I had originally thought that we set up those fds only inside the
test_expect blocks, but it is the redirection 2>&4 that we set up there;
you can always use fd 4 as necessary).

It does incur a useless "cat" when we are not verbose, but I don't think
that's a big deal for the error path like this.
