Done.

Yep, make check eventually called me on it - it stemmed from me not
re-running 'make check' after 'make rpcgen' prior to posting the series.
I'm wondering if we should make the 'make rpcgen' target smart enough
to also update remote_protocol-structs, thus making this one of the
generated files, or whether keeping the manual step in the loop is nice
for forcing the developer to remember that the patch is intentionally
adjusting the wire protocol.
Given your ACKs on the rest of the series, and the small extent of the
v3 diff listed above to address your comments, I have pushed the series.
