Commenting on my own mail...
Rereading the BIP, it occurs to me that the private derivation is
actually intentional. So:
(m/i/j/k)*G = (M/i/j/k), but (m/i'/j/k)*G <> (M/i/j/k) (M/i'/j/k => ERROR)
But: ((m/i')*G)/j/k = (m/i'/j/k)*G
So, the motivation for the private derivation is to avoid the known (K,
c) and known k_i => k known too! I fear that many will fall in this
trap, though...
