[PATCH 0/2] Avoiding errors when partial cloning a tagged blob

When cloning a repository with a tagged blob (like the Git repository) with --filter=blob:none, the following message appears:

        error: missing object referenced by 'refs/tags/junio-gpg-pub'

and the resulting repository also fails fsck.

Patch 1 fixes the protocol documentation and the server side of Git, and patch 2 makes clone error out when such a situation occurs.

An argument could be made that we should not merge patch 2 just yet due to the fact that some server implementations (such as Git and JGit) still exhibit the old behavior, and the resulting clones (albeit failing fsck) are still usable, because when attempting to load the blob, Git will automatically fetch it. I'm on the fence about this, and have included patch 2 in this patch set nevertheless for completeness.

  upload-pack: send refs' objects despite "filter"
  clone: check connectivity even if clone is partial
