Fair enough.
Whatever the approach, I hope argparse can be made to support this through a
simple, documented interface. I had to grovel through standard library code
to figure out what to override and what to duplicate in order to get the
output I want. That seems like a needlessly high barrier for such a common
(and apparently oft-requested) format.
