Perhaps something like this.

The overly long lines are getting a bit annoying but I do not
offhand think of a good way to shorten them.

Also, having to assemble the message in a buffer and emit them all
once with ("%s" % sb.buf) is a highly annoying pattern.  Perhaps
given enough examples, somebody will come up with a simpler API to
do the same thing, but that is not in the scope of this series.
