Well, I designed the commit to make that easy, so go ahead.  I guess that convention might be clear enough to someone who's not me to make it useful in general, but I'm not totally convinced it wouldn't be better simply to mark all code examples/fragments with `>>>` and be done with it (if the alternative of nothing everywhere is unpopular).

I do agree, there were definitely odd cases where I wasn't happy with the results of 9e4a951
