soliditySHA3 multiple bytes32 encoding issue

See original GitHub issue

It seems soliditySHA3 does not handle properly case when multiple bytes32 are involved. Steps to reproduce below:

abi.soliditySHA3([ "bytes32", "bytes32" ], [ "Volume", "Volume" ]).toString('hex'); returns: 8239dae94d559efaf979a8ffdb349ed1d13c6636d28ab641f43ae2bc0c0b985a

Yet,

contract TestTightHash {    
    function coded() constant returns (bytes32) {
        return keccak256(bytes32("Volume"), bytes32("Volume"));
    }
}

coded() returns 0x7ab276f38b269dc879fb051ca72ac238c1a03c2db62bbd7a499c1dd822c3e020

Also confirming this issue, you must install from master for soliditySHA3 to work properly. I recommend publishing the latest version to npm.
