    Preserve page anchors across login tangents
    
    Browsers carry over the anchor upon receiving a redirect response.  Take
    advantage of this by appending any anchor the login page has to the
    form's action.  When the login form is submitted successfully, a
    redirect is issued and the browser carries over the anchor as intended
    for the original page.
    
    Confusion might arise if the login page ever shares an anchor name with
    deeper pages.
    
    Unfortunately there's no way to get at the anchor from the server side
    at the time of tangent, otherwise we could simply stuff it into the
    NextPage entry and be done with it.
