K8S tutorial: cue cmd ls and cue cmd dump do not produce any output

I am not sure if this is pilot error, or a recent commit changed something, but I can't see any objects being listed or dumped.

cd cuelang/cue/doc/tutorial/kubernetes/manual/services
cue cmd dump ./...
cue cmd dump
cue cmd ls 
cue cmd ls ./...

None of the above commands produce any output. cmd ls|dump works if I specify a path to a directory. For example - this works:

cue ls frontend/waiter 
Service         frontend        waiter
Deployment      frontend        waiter

Is this expected behavior?

Not a pilot error. It's a regression. I'll push out a fix shortly.
