Why is it bad to commit lines with trailing whitespace into source control?

Question

Why is it bad to check in lines with trailing whitespace to your source control? What kinds of problems could that cause?

Answer 1

Yeah, I sort of agree with the other posts, but I would add that it's not bad per se. It is not a great practice, but that's the sort of thing that happens and you just sort of sigh and get on with things.
