24 * Rewrite of WantedPages, which uses PageList and prints the references, not just the count.
25 * It disables r1.6 but is more explicit, and of comparable convenience.
27 * A plugin which returns a list of referenced pages which do not exist yet.
28 * All empty pages which are linked from any page - with an ending question mark,
29 * or for just a single page, when the page argument is present.
31 * TODO: sort pagename col: disable backend fallback
