I have a feeling that you are equating two subprojects that
happens to have the same upstream URL the same, and if that is
the case I think that is a mistake.

If you were doing an efficient cgi script that renders history
of git managed projects, binding git as its subproject, and that
system can be built with either 'maint' (i.e. 1.5.2 series) or
'master' (i.e. ultrastable WIP towards 1.5.3), even though they
both might come from git://git.kernel.org/pub/scm/git/git.git/,
I think they should be registered as two separate logical
subprojects.

The .gitmodules file might have:

	[module "git-maint"]
        	path = git-stale/
        	url = git://git.kernel.org/pub/scm/git/git.git/
                ;; branch = maint

	[module "git-master"]
        	path = git-stable/
        	url = git://git.kernel.org/pub/scm/git/git.git/
                ;; branch = master

and two paths (git-stale/ and git-stable/) in the superproject
tree would have commit object names from the named branches.
