With the new translation scheme, the generated output has to be generally interpreted under the semantics of the logic of here-and-there. Horn programs are an exception because for those, the classical logic and the logic of here-and-there coincide.

However, for programs with negation or choice rules, the translation obtained with the new scheme must not be understood in terms of classical logic. In this case, a warning should be printed that explicitly states that the output is only valid if understood in the logic of here-and-there.

Implemented for cases where anthem finds a choice rule or negative literals in bodies.
