Bisection handles nonlinear history very well. I did not say it doesn't handle nonlinear history well. I said it assumes that the history is linear (it's inherent to the notion of "bisecting"). Indeed, in practice the way Git turns the non-linear history into a linear pseudo-history usually works very well. But there are no miracles. Stefan
