  ## OK, so this is a massive cheat, but otherwise testing that out-of-range
  ## coordinates are rejected is really hard.  Pick A = (0, 1), which is the
  ## identity in E.  Then n A = A for all n; in particular, H(R, A, M) A = A
  ## for any choice of R and M.  Furthermore, R = R + H(R, A, M) A for any R.
  ## Let's pick R = A = (0, 1), because that seems to be working out for us.
  ## Then s P = R + H(R, A, M) A exactly when s = 0 (mod ℓ).
  ##
  ## This is obviously a really daft choice of public key for security,
  ## because the following is a completely general-purpose signature for all
  ## messages.
  ##
  ## Why bother, you ask?  Well, because (0, 1) is one of the few points
  ## which has a reduntant representation.  So we can use this to check that
  ## we're correctly rejecting signatures which aren't in normal form.
