color: turn on by default (but for windows) Color support is all in core for a couple of months. I've browsed the bug tracker without finding any blocker bug. So I'm moving forward and enable color on by default before '4.2-rc'. In the worse case, having it on in the release candidate will help us to find blocker bug and we can turn it off for the final release. I remember people talking about issue with Windows during the freeze so I'm keeping it off by default on that OS. We could do various cleaning of the color used and the label issued. However the label are probably already in our backward compatibility envelope since the color extensions has been around since for ever and I do not think the color choice themself should be considered BC. So I think we should rather gives color to all user sooner than later. A couple of test needs to be updated to avoid having color related control code spoil the tested output.
