But I think we can't do much checking for the sparse-oid. We currently accept not just a hex oid, but any name. And I think that is useful; I should be able to say "master:sparse-file" and have it resolved by the remote side. So it really is "any name which is syntactically resolvable as a sha1 expression". At which point I think you might as well punt and just wait until we _actually_ try to resolve the name to see if it's valid. I'll work up what I sent earlier into a real patch, and include some of this discussion. -Peff
