I think that the proper place for that would be supermodule _index_. The supermodule tree would have commit entry, and the index would have symbolic branch (and perhaps some infor about where to find refs for submodule).

This I guess breaks index abstraction slightly, but on the other hand allows for tracking non-HEAD branch of submodule, and for submodule to not know about supermodule at all...
