How about adding a new flag to "git-rev-list", to make it count both ways? Doing this whole

	nr = $(eval "git-rev-list ... | wc -l")
was ugly to begin with, and you just made it doubly ugly.

And the thing is, "git-rev-list --bisect" will obviously already have calculated these numbers just to _pick_ the revision in the first place, so it's a bit sad then execute it twice more (giving it back the result *it* gave us in the first place!).

So we could perhaps change the original
	rev=$(eval "git-rev-list --bisect $good $bad -- $(cat $GIT_DIR/BISECT_NAMES)")
with something nicer.

(In fact, I would also suggest we drop or try to fix BISECT_NAMES support, while at it - it never really worked, and iirc it was partly exactly *because* of the end-condition not being handled right).
