Subject: i.grey.scale and FP maps

Platform: Linux/Intel
Linux distro: SuSe
grass downloaded at: CVS Server, Germany
grass sources source: yes, I am using the latest GRASS from CVS

Using i.grey.scale on FP maps leads to a stripy image:

r.mapcalc test="row()*1.2"

i.grey.scale test
d.rast test

The algorithm should be similar to 
r.colors map cols=grey.eq

(or not?) r.colors doesn't allow to run cols="grey.eq" on FP maps.
This looks a bit confusing.
