forwardLines

Moves @count lines forward, 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 backward by 0 - @count lines.
