Sigh, yes.  I'll document that CNTRL-C is A. deprecated and B. only
valid out side of other packets.
As an asside, quoting CNTRL-C is tricky.  The X packet's existing
mechanism adds rather than subtracts a bit.

Fixing this would probably occure at the same time that the protocol is
extended to include support for HOST->TARGET input packets (reverse of
the O packet).  CISCO already has a tacky implementation, recent
event-loop changes make a more general solution possible.
