There is one difference between is_child and the ancestors functions: How
they handle the case where the path is the ancestor itself.
The is_child function returns NULL, while is_ancestor returns true.
Skip ancestor removes the ancestor (prefix) and returns "" for the ancestor
itself and leaves paths that don't have the ancestor as-is.
