		// for the last character in a line. However, when
		// writing a character (except a new line) that causes
		// a line wrap, the position will be advanced two
		// places.

		// So, if we are stopping at the end of a line, we
		// need to write a newline so that our cursor can be
		// advanced to the next line.
