Section 3.1 says:

Total Length is the length of the datagram, measured in octets,
including internet header and data.  

It should say:

Total Length is the length of the datagram or fragment, measured in octets,
including internet header and data.  

Notes:

Section 2.3 makes it clear that during fragmentation the total length field is corrected to the length of the fragment. Wording such as "break a datagram into an almost arbitrary number of pieces" implies that "datagram" means the entire original packet. Thus, without the proposed correction, one may be led to believe that the total length contains the length of the original datagram.
