    // are on a local task or any other child link. However, if we are on a
    // default local task (e.g., node/%/view), then we do not want the tab root
    // link (e.g., node/%) to appear, as it would be identical to the current
    // page. Since this behavior also needs to work recursively (i.e., on
    // default local tasks of default local tasks), and since the last non-task
    // link in the trail is used as page title (see menu_get_active_title()),
    // this condition cannot be cleanly integrated into menu_get_active_trail().
    // menu_get_active_trail() already skips all links that link to their parent
    // (commonly MENU_DEFAULT_LOCAL_TASK). In order to also hide the parent link
    // itself, we always remove the last link in the trail, if the current
    // router item links to its parent.
