Before the refspec was passed down into the submodules,
we'd just invoke "git push" in the submodule assuming the user
setup a remote tracking branch and a push strategy such that
"git push" would do the right thing.
And because the submodule is configured independently, it
doesn't matter which branch you're on in the superproject.

Looking at the test[1], you run "git push --recurse-submodules"
without any remote/branch that was called out in the commit
message[2] to not have changed. Is that understanding correct?

Looking at the test cases of [2] we did not test for explicit
"still works with no args given", though one could have expected
we'd have a test for that already. :/
