[PATCH 0 of 1] color: replace \r\n with \n in diff output

[Eduard Stefan]

Hi,

I know that the color extension was further developed, but I guess that the ANSI sequences color mode works the same as in Mercurial 1.5.4

Of course, the attached patch solves my problem, but I don't know if will impact something else, so any feedback and/or improvements are welcome.
