Rusty Russell a00179d557 doc, wiregen: use SHA256 stamps instead of git versions.
This should be more robust in future: we SHA256 all of the deps.
For wiregen we prefix with EXPERIMENTAL_FEATURES, since it can effect them.

.SH NAME
lightning-signmessage - Command to create a signature from this node
.SH SYNOPSIS
\fBsignmessage\fR \fImessage\fR
.SH DESCRIPTION
The \fBsignmessage\fR RPC command creates a digital signature of
\fImessage\fR using this node's secret key\. A receiver who knows your
node's \fIid\fR and the \fImessage\fR can be sure that the resulting signature could
only be created by something with access to this node's secret key\.
\fImessage\fR must be less that 65536 characters\.
.SH RETURN VALUE
An object with attributes \fIsignature\fR, \fIrecid\fR and \fIzbase\fR is
returned\. \fIzbase\fR is the result of \fIsignature\fR and \fIrecid\fR encoded in
a style compatible with \fBlnd\fR's \fBSignMessageRequest\fR (\fIhttps://api.lightning.community/#grpc-request-signmessagerequest\fR)\.
