Because of the way GRASS works, it is necessary to switch between mapsets.
i.e., a display command will only work with the current environment and an
accessible mapset. Any operation that changes something (e.g., i.group) will
only work in the current mapset.

However, with more experimentation, it looks like g.mapset won't work as a
way to do this. I've had to revert to using g.gisenv
set=LOCATION_NAME=[xy_location].
