I want to know the answer to the following question:
Why is adding two characters at the ned of a line problemsome?
All the background I'm provided with is that "The original Macintosh OS, Apple DOS, and ProDOS, on the other hand, used carriage return (CR) alone as a line terminator; however, since Apple replaced these operating systems with the Unix-based OS X operating system, they now use line feed (LF) as well.". Is that enough to answer the question?
