Agreed, but this test case shouldn't produce the warning because there's always an active prefix that has a non-LABEL directive.  Or did I miss something?

I thought the point of the "shared label prefix" use case was to show a case of false positives.  However, the examples that @SjoerdMeijer cited should produce the warning because they only use LABEL directives and thus are not legitimate use cases of LABEL.
