Rusty Russell 90b861076d bkpr-report: enhance tag syntax from {tag:replacement} to {tag?if-set:if-not-set} 
This is more powerful, but we need to do this before release.  It lets
us do things like: {credit?+{credit}:0} to only put a `+` in front of
no-zero credit, and {txid?TXID {txid}:Outpoint {outpoint}} to print
either `TXID xxx` or `Outpoint xxx`.
