Exactly what I was saying.

Yeah, ESC is rather obviously a 'control' mode.  What I was thinking is 
that it would end only at the same ESC code again--a toggle--which 
would/might make the control codes themselves a bit shorter and sweeter. 
Or not.  Maybe it really is easier to have the codes self terminate. 
Anyway, that's never going to change of course, but interesting to think 
about.
