(Of course it also could recognize and correctly evaluate the statement as intended, but that's a matter of design and not the issue here.) >How-To-Repeat: see above >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
