Re: [PATCH 07/16] git-read-tree: take --submodules option

If you were doing an efficient cgi script that renders history

'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.
  

I agree strongly with this, and it's another good reason that we have to 
be able to use something other than the URL as the key to look up a 
subproject's repository location. If you use the URL it is impossible to 
differentiate the two subprojects in this case.
