In some scenarios, users may want more history than the repository offered for cloning, which happens to be a shallow repository, can give them. But because users don't know it is a shallow repository until they download it to local, we may want to refuse to clone this kind of repository, without creating any unnecessary files. The '--depth=x' option cannot be used as a solution; the source may be deep enough to give us 'x' commits when cloned, but the user may later need to deepen the history to arbitrary depth. Teach '--reject-shallow' option to "git clone" to abort as soon as we find out that we are cloning from a shallow repository.
