Yes, and no.. submodule update "checks out" the SHA of the commit in the
reference of the superproject. It doesn't fetch or clone anything. What I'm
asking is if there's a way to, give that I have the superproject (shallow
clone, or partial history) to first fetch/clone the SHA of referenced in
the superproject *only* and then update to that fetched SHA *only*.
