What about submodule/.git/refs/supermodule/commit12345678, where "12345678" is 
the hash of the supermodule commit?  This gives a convenient route in the 
submodule to which commit contains that commit from the submodule; but 
doesn't write anything into the submodule repository itself.  It's just a tag 
with a different intent.
