[wcsplus] Unidata WCS error

Hello Unidata folks,

I'm using your implementation of WCS 1.0.0 as a useful reference point as I 
change our 1.1.0 server to accept 1.0.0 (+) requests.

Anyway I noticed a minor error with the DescribeCoverage  operation. The spec 
says you should be able to request multiple coverages in a comma-separated 
list.

i.e.
http://motherlode.ucar.edu:8080/thredds/wcs/galeon/testdata/RUC.nc?request=DescribeCoverage&version=1.0.0&service=WCS&Coverage=Geopotential_height,Geopotential_height_zeroDegC_isotherm

However this raises a service exception, and furthermore the exception comes 
back as a file with the name 'RUC.nc' -  which confused me a bit :)

Reqeusting a single coverage works fine.

Cheers

Dom
