Review Board does not handle files with ^M characters at end of line.
Review Request #826 — Created April 20, 2009 and submitted — Latest diff uploaded
This is a patch for http://code.google.com/p/reviewboard/issues/detail?id=1071 that I had reported. The idea is to make post-review and diffviewer intelligent about lines ending with \r\r\n pattern. All we have to do is to convert those to a simple newline.
Tested this at my work, looks fine so far.
