[GRASS5] BUGS: r.null on reclass, would mess up original...

In BUGS, it lists as [RC] the inability to run r.null on reclass rasters.
The problem is, if r.null was run on the reclass raster it would alter
the original and any other reclass rasters of the original.  So, there are
two basic approaches, let the user make a raster out of the reclass that
isn't a reclass (e.g. `echo 'newmap = reclass' | r.mapcalc`) or have
r.null do this for them.  With the second, a new raster has to be made
and what do you name it?  If you name it the same as the reclass and
blow away the reclass, is that okay?

IMHO, this "bug" isn't a big deal and should be downgraded or removed.
