The new switch passes the pathspec to `git submodule update --init`
which is called after the actual clone is done.
Additionally this configures the submodule.defaultUpdatePath to
be the given pathspec, such that any future invocation of
`git submodule update --init-default-paths` will keep up
with the pathspec.

--[no-]shallow-submodules::
All submodules which are cloned will be shallow with a depth of 1.
