When Michael designed the 4.0 color tables, I stressed how nice and
simple the 3.0 format was, and that somebody was going to want the
old format.  So I urged him to provide backwards compatibility.  I 
am happy to say that it is there.  All you need to do is
set the environment flag:  FORCE_GRASS3_COLORS  and then 
any color tables that are created will be written in that format.

I think a g.resample will force the color table to be rewritten as
well as the cell file itself.
