Ah, that would do it. Or I guess any follow-up fetch. I'm still having trouble convincing submodules to fetch _just_ the desired sha1, though. It always just fetches everything. I know there's a way that this kicks in (that's why we have things like allowReachableSHA1InWant), but I'm not sufficiently well-versed in submodules to know how to trigger it. -Peff
