Thanks for the context.  I clearly just haven't followed the evolution.
Certainly looks like a solid improvement.

Think the last piece I'm missing is: how does one edit a .rst document
without having to know to sprinkle syntactic sugar around?  Does emacs
have a ReST mode?  If not what client interface are people using to
properly change these documents?

(apologies if this is all spelled out nicely in Documentation/
somewhere, but please help this man learn to fish).

Thanks,
Mike
