+       * info/session.c (_scroll_forward, _scroll_backward): Set point 
+       at beginning (resp. end) of node if going backwards (resp.  
+       forwards) failed.  Change since Texinfo 5.2 reported by
+       Benno Schulenberg.

        * info/session.c (forward_move_node_structure): Don't go down a 
        menu for a dir node.  (Broken since 2015-07-13 when N_IsInternal 
        ceased to be set for dir nodes.)
