- no existing unit tests for it, and as the choice is up to the server, it is hard to create tests
- no clear reason to want to use p2sh-nested scripts here, aside from curiosity
We accept either when decoding - this only changes what we use when encoding.
Single quotes are annoying to use in a shell, as they often need to be escaped.
- send to address
- in new channel
