When code or comments are submitted all carriage returns should be removed to ensure diff computation does not encounter errors.

Don't we want to track changes in carriage returns?

... what kind of code are you reviewing that this would matter for?

[spratt]

New lines are an important part of code formatting. I suspect that this bug actually means to standardize on newline characters to mark newlines, which is fair.

Yeah, I remember talking about this. Silly bug.

[psimonyi]

Normalizing all line breaks seems like a good idea.
