Eric / Russell,

Do you or others who get the Zen of GRASS better than I think r.in.gdal ought
to be writing a greyscale colortable for imported files without a colormap?
Should it only do this for multiband images?  Only for 8bit images?

I would be happy to make changes, but I don't want to imply color tables where
they don't exist unless it is widely accepted as the correct thing to do.

Best regards,
