2. BreakLine() does just discard the first line (wreaking total havoc) any
more
3. ScrollToCursor() actually scrolls to cursor
4. style change affects the first line too - and since the first time, style
doesn't change mysteriously any more after second Clear()
5. word cursor movement even better (did I get it right this time?)
