The SPARQL MINUS operation requires that outer vars that don't appear in patterns (EPVPatterns) should not be included in bindings. This means that the get-vars function should not be recursing into FILTER or BINDING. That will require a new operation, which is essentially the same as the existing one, but which returns nothing for filters.
