print P2WSH redeemScript in getrawtransaction if it s not a pubkey

czzarr commented at 3:12 pm on September 30, 2016: contributor

This PR adds code to print a readable asm version of the redeemScript of a P2WSH input in the getrawtransaction RPC call which is useful to explore that kind of transactions.

Example (on testnet3): ./bitcoin-cli getrawtransaction cd56a4b017bf5aeeb86e1397ac91bb9b4ee091d3be1c89b11b08c196468464bf 1 will output the following (note the new redeemScript key):
