[RFC/PATCH 0/3] use '--bisect-refs' as bisect rev machinery option

[Christian Couder <chriscool@tuxfamily.org>]

So I suggest to use '--bisect-refs' instead of '--bisect' as the new
bisect revision machinery option, because otherwise I think we get a
regression when we call "git rev-list --bisect BAD --not GOOD" and we
are already bisecting with bisect refs different than BAD and GOOD.
This also simplifies the code a little bit.

I had a look at using '--bisect-refs' in the git bisect helper instead
of collecting the good and bad refs in bisect.c::read_bisect_refs(),
but I gave up because I think we need the good and bad refs anyway for
other purposes like checking that all good refs are ancestor of the bad
ref. So I think we would not gain much if anything there.

If this is ok then the next steps I can do is add some documentation
and tests for the new '--bisect-refs' option.
