Serge,
The ntp-dev version says 5p113, but I can't confirm this is the same as
the current snapshot. In any case, you need to set the minimum average
headway/system minimum poll interval to 3 in both the server and client;
otherwise, the server will declare a rate violation and toss you a KoD.

Is section 6 in RFC 4330 a figment of my imagination then?

Nope, that is your new client. Mine is a primative ascii based client which
just reports what it sees. No special encoding is needed for a blank.

That happens when you reply to a MIME Quoted-Printable posting that has
trailing spaces, using a user agent that doesn't understand MIME. Mine
will have trailing spaced so that suitable clients will
