The only patch that removes these comments

        ;; FIXME: We need to additionally return the info needed for the
        ;; second part of completion-base-position.

        ;; FIXME: We should pay attention to completion
        ;; boundaries here, but currently
        ;; completion-all-completions does not give us the
        ;; necessary information.
