Stefan-
I agree with you, however, this started out as a direct quote from the spec
:
draft-ietf-http-v11-spec-rev-06: 10.4.14 413 Request Entity Too Large
The server is refusing to process a request because the request entity is
larger than the server is willing or able to process. The server MAY close
the connection to prevent the client from continuing the request.
It seems the 413 is a special case of 4xx.

draft-ietf-http-v11-spec-rev-06: 10.4 Client Error 4xx
If the client is sending data, a server implementation using TCP
SHOULD be careful to ensure that the client acknowledges receipt of
the packet(s) containing the response, before the server closes the
input connection. If the client continues sending data to the server
after the close, the server's TCP stack will send a reset packet to
the client, which may erase the client's unacknowledged input buffers
before they can be read and interpreted by the HTTP application.
