Several updates to BIP62 - #117
Conversation
Clarify that BIP62 rule 6 (clean stack) only applies after potential P2SH redeemscript evaluation. Applying it before the redeemscript evaluation means that every P2SH script will fail it, as P2SH by definition uses an unclean stack (to specify the redeemscript inputs).

@luke-jr I've got a use-case for executable scriptSig content to be able to sign how much fees a tx spends, among many other cases.

And yeah, I think only allowing pushdata ops in P2SH scriptSigs was a mistake.

Ok, removed rule 2 being mandatory.

Removed the hashtype requirement (as it's not required for malleability protection, and may be useful otherwise), and added a clarification that even non-evaluated CHECKMULTISIG signatures need to be strict DER (even though the implementation of the opposite is easier, the semantics become more complex to explain). Thanks to @petertodd for pointing that out. |

Closing this - IIRC BIP62 is retracted |
We dropped reference 1 and 2 during the split, and the offset numbering is causing a bit of head-scratching. This renumbers the reference. Closes bitcoin#117
