[GRASS-stats] Error when starting grass from R (grass installed thru osgeo4w)

[Roger Bivand]

Note that rgrass7 has not been tested on OSGeo4W for many years, so the logic differences from Windows may no longer hold. Using Live has often been a better choice, but as I never use QGIS, I've no experience. Reports on issues with OSGei4W welcome.
