    tab: after loading, no need to scroll to cursor if already at start
    
    Especially useful if the org.gnome.gedit.preferences.editor
    restore-cursor-position gsetting is set to false, and if the file is
    loaded without specifying a position.
    
    In that case the cursor will be placed at the start, so no need to setup
    the idle+timeout.
