patch: don't separate \r and \n when colorizing diff output...

patch: don't separate \r and \n when colorizing diff output When displaying diffs, \r at the end of a line is treated as trailing whitespace. This causes an ANSI escape code to be inserted between \r and \n. Some programs, such as less since version 530 (maybe earlier, but at least not version 487) displays ^M when it encounters a lone \r. This causes a lot of noise in diff output on Windows, where \r\n is used to terminate lines. We avoid that by treating both \n and \r\n as end of line when considering trailing whitespace.
