I've had the same problem as the OP and the idea of adding a syntax rule to recognize log lines and highlight them as comments crossed my mind as well. Then I remembered I saw a perl module on CPAN once that allowed you to write comments in a special way that would be logged. I can't seem to find it after ~10 minutes of searching but it did look interesting so if this rings a bell for someone else, please post a follow-up.
