    open: make non-POSIX errno value more apparent
    
    In the errno list, add an explicit note and reference to the note in the
    STANDARDS section.
    
    When O_NOFOLLOW is specified and the target is a symbolic link FreeBSD
    sets errno to a value different than that specified by POSIX.  Commit
    295159dfa3ed added a note to this effect, but I missed it when reading
    through the list of errno values.
