Not at all. See "Bisection algorithm discussed" in [1]. `git bisect'
would be very dumb if it wouldn't take advantage of merge commits.
As for bisecting Emacs, it's a real PITA because there are so many
broken commits plus you really need a full rebuild for each step to
avoid false results.
One thing that would be useful is a list of bad commits on a format that
could be easily used with `git bisect skip'.
