`man 2 sysctl` issue

[Kent Watsen]

`man 2 sysctl` shows:


    KERN_SEMINFO_SEMMNI (kern.seminfo.semni)
        The maximum number of semaphore identifiers allowed.

    KERN_SEMINFO_SEMMNU (kern.seminfo.semnu)
        The maximum number of semaphore undo structures allowed
        in the system.


But when using sysctl(8) or /etc/sysctl.conf, a couple variables need an extra 
'm':
  
    semni --> semmni
    semnu --> semmnu

Is this intentional?
