Rados Swift API handles prefix differently than Openstack Swift
If I have a test container with a file a/b/c.
With Openstack Swift, if I run swift list --prefix=a/b/c --delimiter=/ test, I get the ["a/b/c"] array
With Ceph RadosGW, I get an empty array.
I created the following patch : https://github.com/ceph/ceph/pull/5828
The Swift test suite (http://docs.openstack.org/developer/swift/development_guidelines.html#testing-guidelines) does not show any regression.
