If a cycle has length 1, don't enumerate the single cycle entry; instead just mention "refers to itself". For instance, for an invalid recursive type T we now report: invalid recursive type: T refers to itself instead of: invalid recursive type T T refers to T Adjust tests to check for the different error messages.
