From what I understand (with my limited skill set),  $wf->Msg is an alternative syntax for wfMsg. I don't know how it could be used to solve the raised issue. If it can be used to both; make the link go to a local page and make the link work well for all combinations of user language/content language (with falling back to EN if there's no local help page), then I'd appreciate it if this requests would be closed for someone more experienced to grab and resolve the related tickets.
