When rev-list is writing E out, it does not know it is a descendant of something it already emitted (i.e. C) because it hasn't looked at F nor checked its parent yet. So asking for (-3)F may be fine but I think (-3)E is just a fantasy. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
