TextIter.backwardVisibleLines

Moves @count visible lines backward, if possible (if @count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn’t move, or moved onto the end iterator, then %FALSE is returned. If @count is 0, the function does nothing and returns %FALSE. If @count is negative, moves forward by 0 - @count lines.
