 	git submodule add dir0/dir1/init

Is supposed to add the repository already checked-out in dir0/dir1/init as a
submodule, at the same location.

 	git submodule add init dir0/dir1/init
    
Would clone dir0/dir1/init at ./init and add ./init as a submodule. This is
actually what the current git-submodule (wrongly) does.
