There is a space between each repeat and a newline after each property
printed. It makes sense to suppress the space for binary output and I
think an option to flick this switch either way might be in order, too
(even something to select a new separator char?). Something else for
the todo once this patch set is in perhaps.

I suppose we need to be a bit careful not to build out the pier too
far until we have some pedestrian traffic.

Did you see patch set 3?

Simon
