;; So that help buffer links do not open in the help popup, we need to redefine these
;; three button types to use `switch-to-buffer-other-window' rather than
;; `pop-to-buffer'. Instead of lambas these help-functions should be function symbols,
;; so that we could advise those instead of clumsify redefine these button types.
