Commit message should wrap at 68-72 columns.

This doesn't play well with Christoph's cleanup series which fixes
up all the confusion with internal versus API flags. I guess the
namespace is part of the attribute name, but I think this would be a
much clearer conversion when placed on top of the way Christoph
cleaned all this up...

Have you looked at rebasing this on top of that cleanup series?
