[gdal-dev] gdal_translate file naming for sds and HDF4 files

[Jonathan Greenberg]

Thanks -- I did notice it was an earlier version (switching to the latest
OSGeo4W), I apologize for not checking the latest, but as Etienne
confirmed, the bug seems to be there in the latest as well.  The HDF files
from various sources are so odd when it comes to naming layers, that this
SDS argument is really helpful (if it would name the files correctly).

Speaking of -sds --> perhaps I can request that gdal_translate allow for a
layer # flag rather than the full layer name for subdataset files?  Is this
relatively easy to implement (since gdalinfo seems to already have the
capability)?
