Add the --depth option to the add and update commands of "git submodule", which is then passed on to the clone command. This is useful when the submodule(s) are huge and you're not really interested in anything but the latest commit. Tests are added and some indention adjustments were made to conform to the rest of the testfile on "submodule update can handle symbolic links in pwd".
