/**
 * The return url of a detail page's own actions.
 *
 * Every action on this page has to hand on the "r" it was given, not the url of the page it sits
 * on: return_url() encodes the current request, so a send button would send the reviewer back to
 * the detail page they are already looking at - and because the send controller redirects with
 * that same "r", "zurück" then points at the detail page itself and appears to do nothing, one
 * nesting level deeper per click. forwarded_return_url() is what keeps pointing at the list.
