There is ongoing discussion on the grass-stats list:

http://lists.osgeo.org/mailman/listinfo/grass-stats

The GRASS 7.0 RC1 is where many parameter names have been changed. The 
changes are quite large, so the current R spgrass6 package will only 
handle GRASS 6 up to GRASS 7.0 beta, while the new spgrass7 (in the 
spgrass project on R-Forge) is being matched to changes in GRASS 7.0 RC*.
See:

install.packages("spgrass7", repos="http://R-Forge.R-project.org")

This is thanks to input and work by Rainer Krug and Markus Neteler. RC2 
should be out soon too. spgrass6 will shift to maintenance mode only 
shortly after GRASS 7.0 is released, but will stay available.

The parameter name changes are on:

http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Optionschanges

We have not checked against GRASS trunk. I think that your adaptation 
might match the regular 7.* series rather than the development trunk, but 
I agree with Rich that it would be worth asking on the GRASS users or 
developers list.
