thanks for mentioning it was missing. The r.reclass manual is now updated
in SVN to point out this trick.


Helena: some kind soul has added a fail-safe into g.remove, now if you try
to remove a raster which has a reclass based upon it you get an error
message:

GRASS65> g.remove landuse.copy
WARNING: [landuse.copy at user1] is a base map. Remove reclassed map first:
         landuse.copy.reclass at user1

I'm assuming the g.remove -f force flag is there to override that.
Not sure if it notices that there is a reclass based upon it existing
in another mapset (perhaps owned by another user), but I guess you
make reclass maps based on other people's maps at your own risk. ie you
would naturally get mad at them, not the GIS, when they remove it.
