New feature wish: [<URL-SPEC>] anchor-visited-begin = (HTML code) | Anchors (links) in the spooled page that are in the cache and have been visited this session or since invoking wwwoffle --reset-visited-timeline are to have the specified HTML inserted at the beginning (default="").
Rationale: anchor-cached-begin is nice, but one wants to know what has also been browsed already. Browsers these days can differentiate between visited and not visited, but are not able to limit that to start just at the beginning of this session, unless you blow away their history list[?] I'm supposing if wwwoffle -config notices that anchor-visited-begin is set, it will start keeping track of what pages it has served. All done in memory. No need for a file. P.S., maybe an also add a [<URL-SPEC>] anchor-cached-requested-begin = (HTML code) | Anchors (links) in the spooled page that are in the cache and have also been requested for download are to have the specified HTML inserted at the beginning (default="").
