At first, I was worried that this meant that '--color' ==
'--color=none'; so maybe you want this to read "This is the default when
no --color option is present"

Is this the right default? Some GNU programs default --color to
--color=auto; others to --color=always. I'm 50:50 on which default is
better, but it's worth thinking about rather than just blindly picking
one, as we have both GNU styles as precedent.
