I mean, I don't edit or annotate mail messages at all, but I know some
people who do that extensively.  (Hi, François!)  Wouldn't it be
really nice if you could edit/annotate any text in any article buffer?
You read an article in some newsgroup, and there's some useful stuff
in there, so you start editing it and inserting stuff here and there
in the article.  But you want to know which parts you wrote and which
parts were in the original article, no?

And it just now occurred to me that RCS would perhaps be the right
thing here.  The Meta-Edit command would pull the article down into
the cache, and when you edit it, you just commit your edits to the
cached version of the article.  When reading the article, Gnus would
check the latest version out, but have a special viewer that would
colorize the contributions from different people differently.  And,
and...

Er.

Anyway.
