[FWTools] Opening ENVI file in python using FWTools 2.10

[Jeff Ruby]

Thanks much, Frank.  I did a little more investigating.  It looks like my
issue may have been introduced with FWTools 2.1.0.  I tried three different
combinations:

1 - myfile, myfile.hdr
2 - myfile.envi.dat, myfile.envi.hdr
3 - myfile.envi, myfile.envi.hdr

gdalinfo and gdal.Open() work fine for all three combinations on my machine
(WindowsXP 32-bit) with FWTools 2.0.6.

With FWTools 2.1.0:
- The first two combinations both work with gdalinfo and gdal.Open()
- The third one does not seem to work with gdalinfo or gdal.Open()

Regards,
-Jeff
