Hey, David.  I think this is a fine approach, Go with the transitional
"--" separator for one release or so, with a deprecation warning, and
then move to the standard form in the release after that.

I realize the later probably requires more work, since we would have to
replace all print calls with a new function, but I think it's the
cleaner and more elegant solution.  There's no reason to have an output
redirection option for "dump"s and not for any of the other commands.
