"Hi, I made a mistake by using submodules. I don't want to use
them any more, I rather want to:
A) make it a separate git repo again and I'll keep them in sync myself
B) ... "
"I abuse submodules for what git-LFS was designed for, and the
submodule is on a different mount point, please keep the git directory
also at that mount point".
Not sure I agree these problems and the proposed solutions are beautiful,
but that is what people may think of as a fast hack?

So when we want to have a generic function in C ("relocate_gitdir")
for both worktree and submodules, the recursive flag is not supposed
to invoke a submodule specific helper, but a generic helper.
Alternatively we make the function not as generic and claim the
recursive part is submodule specific and we can happily call
"git submodule [un]embed-git-dir" recursively.
