If it is done on the output part, that's ok. Really,
I guess it is ok by me as long as the documentation
warns about not using it in another context.

BTW, also, if stdout is not a terminal on unix, I
don't think you should output the colors (at least
not by default). Most unix apps don't put color
sequences out to pipes, etc.

I'm not sure how to best do this in std.format; this
kind of decision seems like it belongs in std.stdio.
