AFAIK, no. (but see r.his, d.his, d.rgb, i.his.rgb, i.rgb.his, ...)
CMYK is not supported. (but you can process the 4 channels as 4
different n-bit CELL raster maps if you like)

Yes. Blank lines are ok too.

currently lib/gis/color_rules.c uses fgets(), so only UNIX newlines are
accepted. Any reason not to make that use G_getl2()?

an interesting idea, but let's get the color table working first before
we worry about that too much.

(I'm working on a proof of concept shell script first)
