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

[Eduard Stefan]

The correct behavior would be to recognize \r as part of the line separator,
so instead of:
  ESC [0m ESC [0;1;41m CR [0m LF
the output should be:
  ESC [0m CR LF
but I have to search a little more for the right place to make this change.

Have a nice day,
  Eduard
