    Reword address format definition in section 4.5
    
    Let's refrain from mentioning section 6.4 in here, as the format
    is not exactly the same - not all address type field values from
    section 6.4 make sense in NETINFO cell and NETINFO cell does not
    have a TTL value at the end of each address. It's a little confusing
    to suggest that there is a reuse of wire format fragment between
    RELAY_RESOLVED and NETINFO cells.

-   The address format is a type/length/value sequence as given in
-   section 6.4 below, without the final TTL.  The timestamp is a
-   big-endian unsigned integer number of seconds since the Unix epoch.
-   Implementations MUST ignore unexpected bytes at the end of the cell.
+   The address format is as follows:
+         Type [1 byte]
+           * 0x04 - IPv4
+           * 0x06 - IPv6
+         Length (size of Value field) [1 byte]
+           * 4 if Type is IPv4
+           * 16 if Type is IPv6
+         Value [Variable-width]
+           * Address value in network byte order.
+
+   The timestamp is a big-endian unsigned integer number of seconds
+   since the Unix epoch. Implementations MUST ignore unexpected bytes
+   at the end of the cell.
 
    Implementations MAY use the timestamp value to help decide if their
    clocks are skewed.  Initiators MAY use "other OR's address" to help
