Scrolling works with screen lines. When 'wrap' is set and the first line in the window wraps part of it may not be visible, as if it is above the window. "<<<" is displayed at the start of the first line, highlighted with hl-NonText. You may also want to add "lastline" to the 'display' option to show as much of the last line as possible. NOTE: only partly implemented, currently works with CTRL-E, CTRL-Y and scrolling with the mouse.
