These are queued for default, thanks. One small change:

> +            rst.extend(map(lambda l: "    %s\n" % l, doc().splitlines()))

The map + lambda idiom has long-since fallen into disfavor. We now like:

 rst.extend("   %s\n" % l for l in doc().splitlines())

or even:

 rst += ["   %s\n" % l for l in doc().splitlines())]

Fixed locally.
