Nice work! IMO it would be even nicer to have it as part of git grep.
Have a look at Jens branch about submodule checkout:

http://github.com/jlehmann/git-submod-enhancements (enhance_git_for_submodules)

particularly how checkout_submodule() is implemented. It forks a git
checkout inside the submodule. In a similar way you could fork a grep
there. Then you just have to teach the forked grep to prepend the
submodules path.
