rev-parse: add --show-superproject-working-tree
In some situations it is useful to know if the given repository is a submodule of another repository. Add the flag --show-superproject-working-tree to git-rev-parse to make it easy to find out if there is a superproject. When no superproject exists, the output will be empty.
