API incompatibility issue which is found by this test.

Although Amazon S3 respond 400 Bad request if multipart completion request has no part item, Riak CS accept the request.

A response sample from S3.

OK, so it looks like the test is supposed to do the following:

• Initiate a multipart upload
• Send 0 upload parts
• Send the "completed" upload message

Is my reading of this test case correct?

Yes, you're right, Mark.
