testing: in example, empty output not distinguished from missing output

[rsc]

An Example test with no // Output comment is not run, not tested.
In contrast, a test with

  // Output:

by itself should be expected to print no output. Instead it is not run.

Comment 1:

Why would you want to do this? When would a well-written example have no output?

Comment 2:

If it's not valid (I disagree) then it should be rejected outright. It
should never just be silently ignored.
I was putting
// Output:
lines at the end of my example code as a reminder to go back and fill
in the output. Since I knew the code did generate output, I assumed
this would make the example test fail, and in the process of failing
tell me what the output was. But instead the tests passed, so I had to
go back and change them all to
// Output: XXX
