Dear diary, on Fri, Oct 06, 2006 at 08:21:05PM CEST, I got a letter where Luben Tuikov <ltuikov@yahoo.com> said that...

Wow, you caused my GNOME at work to do something totally horrible after me clicking on that link... ;-)

I'm not sure how is RFC2045 relevant - this is from RFC822, RFC2045 does not define those non-terminals.

Show 5 quoted lines

It's a moot point now, but I don't see that - inside qtext, any character can be quoted, so what we do is technically ok.
