That what I think, too... But then I do not understant why the RFC tells us 
that "Lines beginning with periods must be prepended with an extra period"... 
Have I missed something?

That's a good idea, indeed. I have added that to my todo list for the next 
version of my gopher server :-)

That's rather normal - binary data has no "<cr><lf>.<cr><lf>" terminator, it 
just listens until the connection is closed by the server, so I would say that 
there's no surprise there...
By the way, I noticed that some Gopher clients (at least Firefox and Lynx) are 
displaying the "dot terminator" of text files just as it would be part of the 
document. Too bad for them :)
