My solution is attached.  I'm not satisfied with it, I have the
feeling that it could be improved in several places, but it does work.

I TDDed this, but when I got to writing the "Instructions" class, I
couldn't (quickly) come up with a reasonable way of TTDing it.  It
probably means that I put too much stuff in each method, which is
likely where my insatisfaction comes from.
