[Gdal-dev] ENVIDataset::FlushCache is not idempotent for header file

[Carlos A. Rueda]

Hello Frank,

I have just noticed that multiple calls to FlushCache on an ENVI dataset
object will generate a header with repeated header items. I also notice
that the first call inside this method is to GDALDataset::FlushCache()
but perhaps it should be to RawDataset::FlushCache().

Best,

Carlos
