* harbour/contrib/libct/ctwin.c
    * added protection against overwriting right and bottom WBOX border
      directly inside GTCTW so now other screen functions does not have
      to check maximum window coordinates. Please remeber that CTWIN from
      CT3 has a bug which allows to damage top and left border which I
      partialy replicated because peope used it to set window title.
