What is a cross-ref operation?  A worktree is either the primary
working tree for a (non-bare) repository, or something added with
"git add worktree" (i.e. whose .git is not the repository but a
link file into the real repository).  Are you adding another mode
where a worktree points at another worktree and not the repository?
