Well, the plan is to deprecate `ford_fulkerson` and friends in 2.0 (because @ysitu already implemented the Edmonds-Karp algorithm following the new conventions). Thus if we are to remove `ford_fulkerson` anyway I'm not sure that we need to change it's default output for 1.9. Maybe we could consider removing them now, but I'm a bit hesitant because we could be breaking user code; and since in 2.0 there will be significative backwards incompatible changes maybe it is better to wait until then to definitively remove `ford_fulkerson` and friends.
