    inet(3): clarify syntax accepted by inet_pton
    
    The section INTERNET ADDRESSES describes the acceptance of dotted
    values with varying number of parts in multiple bases.  This applies
    to inet_aton and inet_addr, but not to inet_pton.  Clarify this
    section by listing the functions to which this applies.  Move the
    description of what inet_pton accepts into this section from STANDARDS,
    where it is easily missed.  Rename the section to clarify that it
    applies only to IPv4.  (inet_pton also works with IPv6.)
