Hello Tim:
You'll be pleased to learn that we have addressed this issue in our upcoming releases 4.3.6/4.1-ESV-R15 due out 7/31/17; and 4.4.0 due out later this year or early '18.
Took us awhile but we got to it. We also updated the openbsd script as it had the same issue. We like to thank our contributors by citing them in the release notes. If you wish to be recognized in this manner please reply with how you want to be identified.
Thank you for taking the time to report the matter to us, we welcome any future submissions you may make.
Sincerely,
