You may want to look at r.in.gdal, the group file handling is already
implemented there.

In general - do we want to maintain r.in.tiff when r.in.gdal does more
or less the same (eventually group file handling must be added explicitely
for RGB, if needed)? r.in.gdal writes a group file when GCPs are found
within SAR data (CEOS2 driver). This might be "easily" extended to also
generate GCPs from a TFW file.

Just my 0.02 Euro
