Right; I followed the existing options in both fetch-pack and send-pack
(use_sideband, no_done, and others here have the same issue), with the
assumption that the current code was not broken (which may not be true,
if it is simply masked by the fact that in practice everybody happens to
support those older features).
I don't know off-hand whether that is actually a trigger-able bug in the
current code or not. It's probably a good topic for a follow-on series.

Yes. I didn't realize it until Dave mentioned the "innocuous" list. I
think cleaning them up is reasonable, but probably a separate topic.

Right. Not through me having thought about it, though, but by following
the existing convention.
