Yes, I think this is the only way submodules in current git can
be used with the GIT_DIR and GIT_WORK_TREE environment variables:
set them when adding or initializing the submodule and always use
the same settings when accessing them later. Daniel's dotfile
alias achieves exactly that, so his fix looks good. But I agree
the tests should be improved as you already pointed out.
