set_menu_format, menu_format - set and get menu sizes

       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       The  function set_menu_format sets the maximum display size of the given menu.  If this size is too small
       to display all menu items, the menu will be made scrollable.  If this  size  is  larger  than  the  menus
       subwindow and the subwindow is too small to display all menu items, post_menu will fail.

       The  default  format  is 16 rows, 1 column.  Calling set_menu_format with a null menu pointer will change
       this default.  A zero row or column argument to set_menu_format is interpreted as a request not to change
       the current value.

       The function menu_format returns the maximum-size  constraints  for  the  given  menu  into  the  storage
       addressed by rows and cols.
