[GRASSLIST:6078] null color thru r.colors?

[Parviez Hosseini]

Hello all --

I've look through the man pages, and the list archives, but I can't figure 
out how to change the color that null values appear using r.colors.
I can change it using the interactive d.colors, but that is sub-optimal, 
and I'm interested in it for a "r.colors $MAP col=rules" type application.

FYI, the d.colors man page seems out of date, as there is now both 0 and N, 
not just 0.

Thanks,
Parviez
