I _think_ that the right order is

loop over head.next
 if current_node == hlist or vlist then loop over head.list end
 do something with current node
end loop

Additional places to recurse into, depending on application:
* disc nodes (components)
* leader part of glue
* sub_box and sub_mlist subnodes (?)
* box_left, box_right in local_par node
