System V curses works the way you describe, i.e., it can distinguish
between ESC and ESC[A, and return the application a single token for
either input.  What I don't know is how curses implements this.  On my
System V box, you cannot set MIN=1 and TIME=1 to get a .1 second
timeout on a single character read, nor should you be able to,
according to termio(7).  We had a discussion about this very topic
right here a few months back, and I don't think anyone knew how to do
it on System V, even though it obviously can be done.
