/* Test what is printed when Value evaluates a post-condition:
   - function with a body (h below): emit a status, plus message "postcondition
     got status..."
   - function with only a spec: do not emit a status (respect the Kernel's
     green/blue statuses) + emit a message only in case of invalid: messages
     for Valid/Unkown are not informative
   - function with a body, but for which we evaluate the spec (val-use-spec,
     g below): emit the status (otherwise the verification is incomplete),
     emit message only in the invalid case.
   - in the last two cases, do nothing in the case 'ensures \false' (the
     warning is too distracting otherwise)
