Currently git submodule init and git submodule sync fail with an error if the superproject origin URL is of the form foo but succeed if the superproject origin URL is of the form ./foo or ./foo/bar or foo/bar. This change makes handling of the foo case behave like the handling of the ./foo case and also ensures that superfluous leading and embedded ./'s are removed from the resulting derived URLs.
