I honestly cannot remember. Perhaps Peff does? Yes, that matches my understanding. By the time you finish limit_list(), from the "revision traversal" point of view, you have done all the hard work already, sifting commits between the ones that are and are not interesting. I am surprised that whatever you learn only after reaching that point is still helpful to optimize some operations.
