@geomacy as discussed at apache/brooklyn-server#672 (comment) (and this PR only does anything with that merged, else it is safe but no-op) this supports displaying the additional message eg

% target/br catalog add file:///tmp/test672a.zip
Updated io.cloudsoft.cli44:0.12.0.SNAPSHOT as existing ID kbhxoi0ln4
* myTestEnt:0.12.0.SNAPSHOT
* myOtherTest:0.12.0.SNAPSHOT
* testent1:0.12.0.SNAPSHOT

instead of

% target/br catalog add file:///tmp/test672a.zip
myTestEnt:0.12.0.SNAPSHOT
myOtherTest:0.12.0.SNAPSHOT
testent1:0.12.0.SNAPSHOT

but falling back to that latter output if detail isn't available (old server version, or not uploading a bundle/directory)

Looks good to me too! Sorry about late review but wouldn't have had any comments anyway :-)
