Just to be clear, would it look like the following?

e8a6e39ecfbd391a54b9c3329fd3c6e33d745abd refs/heads/bernstein c5c64e3fe48302f0c4581985f9c68d615f7bcb4e refs/heads/master 3fa7ded19a8da868d3af7c942f86358e6720f0c7 refs/heads/submodule /home/sverdool/public_html/cloog.git cloog^{URL} http://www.liacs.nl/~sverdool/cloog.git cloog^{URL}

Is there no code out there that expects the "rev" part to be exactly 40 characters? Or do you propose we put the URL in a blob and put the object sha1 in there. If so, who's going to create these blobs for the git:// and ssh:// protocols? upload-pack?

Thanks for the discussion, btw. I hope we can come up with something that's acceptable to everyone.
