 Do you know what is the future standard of GRASS to script for the

There is ongoing discussion on the grass-stats list:

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:

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.

 Ask on the GRASS mail list; you can sign up at http://grass.osgeo.org/.

If there are syntactic differences I would assume that those in the 
7.1svn
are the future. I've used GRASS (on linux) since 4.0 and current use 
7.1svn
so I've seen many differences over the past couple of decades.
