That explains the funny characters. I had to first "stty discard ''" in
order to "mail" a Control-O in a message--by default it just discards the
line--but then it became obvious that SO made the funny characters display
in pine, and SI made them go away.

Next question: how is it that a Control-N gets into the subject of a
message? Is the sending program really trying to do something else, or is
the transport eating the Contol-O's but not the Control-N's?
