It would be nice if this could continue: "C: I also want these, S: ok, heard enough, C: done, S: another packfile is here"; we should be able to identify the end of the packfile on both ends to resume doing other things. Or, maybe, "C: I also want these single objects, S: here's a thin pack of them", since it's exclusively tags pointing to objects we have just gotten. -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
