 I wanted to add a class to the menu item LI elements for navigation menus
 that have sub menus. This would allow me to do some specific styling such
 as using a background that shows that a sub menu is available on hover.

 I found that adding this support for both the wp_nav_menu and
 wp_list_pages functions was quite simple. So, I put together a patch in
 case it might be a good candidate for core.

 The new classes are menu-item-with-sub-menu and page_item_with_children
 for wp_nav_menu and wp_list_pages, respectively. These class names were
 chosen to closely match the existing navigation classes of menu-item, sub-
 menu, page_item, and children.

 I should note that while making this modification I found that the
 display_element method of the Walker class doesn't set has_children when
 $args is an object, just when it is an array. The patch also handles
 fixing this shortcoming of the Walker API.
