Still I dare claim that moving a cursor up one visible line has nothing to do with the concept of a line delimited by newlines. For the movement, such delimited lines are completely irrelevant. For the movement there is no difference whether there is a newline on the previous visible line or the line was broken due to the width of the window. What I speak about is 'as if' clicking the mouse up one visible line. R
