Code review comment for lp:~ibid-core/ibid/feature-discovery-399667

We use ellipses here, but the usage strings use <foo> notation. Consistency?

Query: what silly fun stuff do you do?
Response: Got it

Perhaps that syntax should work too?

Query: how do i use rot
Response: I'm afraid I don't know what you are asking about. Ask "what can you do" to browse my features

Would be nice if it suggested "Did you mean rot13"?

Haven't looked much at the code yet though.
