Good point. Of course, data.length is a number, so it won't have a newline to worry about anyway. But if you're just displaying the data *string*, the brackets (or choose your favorite delimiter) are an excellent idea:
console.log( '[' + data + ']' );
That would make it obvious if data has a newline or other whitespace.
