       In  order  to  make  menu selections visible on older terminals without
       highlighting or color capability, the menu library marks selected items
       in a menu with a prefix string.
       The  function  set_menu_mark  sets  the mark string for the given menu.
       Calling set_menu_mark with a null  menu  item  will  abolish  the  mark
       string.   Note  that  changing the length of the mark string for a menu
       while the menu is posted is likely to produce unhelpful behavior.
       The default string is "-" (a dash).  Calling set_menu_mark with a  non-
       NULL menu argument will change this default.
       The function menu_mark returns the menu's mark string (or NULL if there
       is none).
       The function menu_mark returns a pointer (which may be NULL).  It  does
       not set errno.
       The function set_menu_mark may return the following error codes:
       E_OK The routine succeeded.
       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.
       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

       These routines emulate the  System  V  menu  library.   They  were  not
       supported on Version 7 or BSD versions.
