Subject: Unset the optional bit for a feature when setting the required bit
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=cb823059fec283851f67cf53455ccdeafb29acba;p=rust-lightning

Unset the optional bit for a feature when setting the required bit

There is no reason to set both, and this currently makes testing
the new BOLT invoice tests slightly harder, so we just unset it.
