It might be enough to rewrite = this BIP to basically say "all pubkeys
executed by all = CHECKMULTISIG opcodes will be in the following canonical
order", followed by some explanatory examples of how to apply = this
simple rule.

OTOH we = don't yet have a standard way of even talking about arbitrary
scripts, so it may very well turn out to be the case that the = above rule
is too restrictive in many cases - I certainly = would not want to do a
soft-fork to enforce this, or even = make it an IsStandard() rule.
