Stuart a general recommendation (in case you are not aware of it): better to
work with data in user-Mapsets and not in PERMANENT.
That is: create a new user-mapset, switch to it and g.copy the "to-be-
processed" material. This way ensures keeping intact the original imported
maps -- mistakes can be very time expensive.
