Hi Mark,

I think so, yes. Clients and servers should both ignore extra CRLF.

Even if the client and the server are are both netcat/stdio the client
or server at their station might want to hold down the enter button to
make some clear room on their terminal.

Similarly and with regards to your section 3.1, I like the way this
first paragraph reads Mark then..

I think the text reads better without giving the flawed example implementation.

In the interest of robustness, client and server applications that are
expecting to read a request or response line should not abjure all
hope and connections if the line is empty (just CRLF). Try again, your
request-line will come, don't abort this connection..
