This is not enough, you would also need to check if the band option or the
k flag is used with r.in.gdal.
In order to keep things sufficiently simple (which the wxGUI not longer
is, but anyway), I would rather suggest to test if the output raster
exists, if not, the GUI should not attempt to display it.
