I really like to see r.colors be able to make grey.eq and grey.log colorscales
with float rasters. When one wants to make a figure for a paper, it will be in
greyscale (most times) and the 'simple' greyscale from r.colors usually is not
as good as it could be.

Carlos,

this would be nice - hopefully Wolf figures out how to enhance
r.univar for extended statistics, this will provide functions
to also enhance r.colors with long standing wishes.
Maybe someone can give Wolf a hand?

This has been implemented by Glynn in CVS some weeks ago. Flags -e and -g
allow to equalize any color table now, and floating point rasters are supported.
