[gdal-dev] difference between -a_nodata and -dstnodata?

[Kyle Shannon]

I believe -a_nodata in gdal_translate sets the no data value as in
GDALRasterBand::SetNoDataValue().  -dstnodata in gdalwarp initializes the
bands with the supplied value, but doesn't call
GDALRasterBand::SetNoDataValue().  I think.
