Actually, I think it's the reverse: without --stdin, name-rev can do a first pass that lets it eliminate a lot of data from consideration; with --stdin, it doesn't know if an item it hasn't seen is going to need some data, and so it's conservative and doesn't eliminate anything, which means that each request is slower, at least until it's cached everything that you turn out to care about. -Daniel *This .sig left intentionally blank* -- 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
