- Roll back cwp.50 because creating a new binding leaves the CM-literal bindings in their old state.
- Don't signal #binding:removedFrom: because it's becoming the literal in CM's to a newly created Undeclared literal with the old name.
- So since we no longer signal removed: don't signal #binding:addedTo: either.
        Renaming is a updating of a binding, not a removing or adding.
