[GRASS-user] does i.landstat.toar expects ALL bands to work properly?

I'm playing around with some Landsat-8 images. After reprojecting with GDAL
(for southern hemisphere), importing and clipping to a smaller area of
interest, I used i.landsat.toar to convert to reflectance.
I'm only using bands 1-8.
When I run i.landsat.toar *without* atmospheric correction, it runs but
gives me an error message about not being able to read band 9, but it does
creates the images.
When I run it *with* atmospheric correction, I get the same error but it
won't calculate reflectance, because it stops at the dark pixel step.
So, two possibilities:
1 - If it is expecting all the bands, this should be in the manual
2 - remove this limitation, by issuing a warning but not rising an error
and stopping the module.
