Comment:

 The request sounds reasonable but I didn't figure out how to pass
 "papszOptions" to GDAL as used in r.external. The magic line in r.out.gdal
 is this:

 {{{
 # r.in.gdal/main.c

         hDstDS =
             GDALCreate(hDriver, output->answer, cellhead.cols,
 cellhead.rows,
                        ref.nfiles, datatype, papszOptions);
 }}}

 but in r.external GDALOpen() is used. Perhaps a GDAL expert can tell us
 the trick.
