Truncated source line warnings

Revisiting an old topic, would it be possible to add a slightly different option to the "truncated_source" -warn flag that ignores comment fields?  We encourage our developers to heavily comment their code, but with "-warn truncated_source" set, there are a lot of false positives when comments that start with the "!" symbol run past 132 columns.

Thanks for considering.

May I suggest instead that you encourage your developers to use free-form source? You wouldn't have this issue, then. New code should never be developed using fixed-form - it encourages errors.

Nothing to do with free-form source

That's only if you ask for standards checking - very different from -warn truncated_source (as mentioned in the OP) which applies only to fixed-form.

Of course, even 132 is non-standard for fixed-form.
