[Edi]

Notepad uses nonstandard (for Unix/Linux) endlines. On top of that, it does not even recognize the normal endlines, so if you open up a text file that uses those, it's all mashed together in one big row of text and probably contains errors too. Notepad is crapware.

So anything that uses the standard endline will work just fine. Personally, I recommend Crimson Editor. It's free for personal use and absolutely kickass for all kinds of things, including coding.
