[GRASS-dev] flag for turning off negative values in r.watershed

 From working with the current version of r.watershed for modeling, it  
would be nice to have a flag that turns off the "feature" that makes  
accumulation values negative if the entire upper end of a watershed is  
not on a map. I understand the rationale behind this, but it would be  
nice to be able to turn it off rather than to have to subsequently run  
r.mapcalc to make a new map from the absolute values.
