r.sum produced result with spaces:
SUM = 8787936.000000

which makes it hard parable for shell scripts:
eval `r.sum rast=soils --q`
bash: SUM: command not found

IMHO there is no barrier to remove this white spaces, so the that result
looks like 

and one can easily perform something like 
eval `r.sum rast=soils --q`
echo $SUM

I allready sent this to cvs - I'm just asking, to be sure.
