No. Not unless you want to simulate it to the point of honoring the
different verbosity settings, which would greatly expand the size of the
patch. We do not try to make the response to "help" look like an error
message, and I don't see the value of doing so here either.
(I think Florian's real problem with the proposed output is that it's
ugly, which I agree with --- the formatting is strange.)
