    cd9660: Apply the file and directory mode masks bits to all 12 access bits
    
    This permits the mask bits to control the upper 3 bits used for setuid,
    setgid, and sticky permissions.  While here, clarify the manpage language
    as non-Rockridge volumes with extended attributes can also supply users
    and groups along with permissions.
