This allows you to say: git bisect start git bisect bad $bad git bisect next to start bisection without knowing a good commit. This would have you try a commit that is half-way since the beginning of the history, which is rather wasteful if you already know a good commit, but if you don't (or your history is short enough that you do not care), there is no reason not to allow this.
