 The problem seems to be that on NetBSD scrl(3)
 
      If a scrolling region has been set with the setscrreg() or wsetscrreg()
      functions and the current cursor position is inside the scrolling region,
      then only the area inside the scrolling region is scrolled.
 
 and otherwise the whole window is scrolled.
 
 ncurses always scrolls the scroll region, regardless of the current
 cursor position.
 
 SUSv2 X/Open curses scrl(3) says that
 
   The interaction of these functions with setscrreg() is currently
   unspecified.
