I'll use this one, thanks.

My intent was to include the fact that we check that the truename is not 
the same, but it's implied heavily enough in your version too.

git clone https://git.savannah.gnu.org/git/emacs.git emacs
ln -s emacs/lisp lisp-symlink

Files under lisp-symlink have vc-backend return nil - visiting any of

Whether we call that "not having a VC backend" is a question of semantics.
