[This is the first of three responses to the "untouch" article that I've
received.  In addition, help arrived from Steve Nuchia and Mike Stump.  -mod]

(Gawd, I hate curses!  I'm working with overlapping windows, and
they're a real pain!)

Each line in a window has an offset to the first and last characters
that are changed called _firstch[y] and _lastch[y].  If you set:
	window->_firstch[y] = _NOCHANGE
the line becomes untouched.

There is also an undocumented call touchline(window, y, startx, endx)
to touch a portion of a line in a window.

Hope I got this right.  Good luck
