This doesn't seem like it should be that difficult to implement.
Round-tripping with

(enriched-encode (point-min) (point-max) (current-buffer))

and

(enriched-decode (point-min) (point-max))

seems to work fine (well, with some post-processing after the first to
get rid of colours, so they're not doubly encoded).

I'm not quite sure that having the `C-c C-c' command be `enriched-mode'
would be all that helpful, though -- was there any particular reason for
that in the feature spec?
