You have to make sure not only the object exists, but also it is reachable by one of the refs. One way to check that would be to ask "describe --all" if it can find a ref that can reach that commit. It would error out if the commit object exists but is not reachable from any of the refs. - 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
