It will work even if o is explicitly set to "", but will not if it is not set at all (which is supposed to imply an empty string "" too). >How-To-Repeat: See description. >Fix: See description. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
