+ modify _nc_New_TopRow_and_CurrentItem() to ensure that the menu's
  top-row is adjusted as needed to ensure that the current item is
  on the screen (patch by Johann Klammer).
+ add wgetdelay() to retrieve _delay member of WINDOW if it happens to
  be opaque, e.g., in the pthread configuration (prompted by patch by
  Soren Brinkmann).
