VStream, structured, formatted text applitude

[Tuomas Lukka <lukka@xxxxxxxxxxx>]

Ok, I think the time is now ripe for an applitude that does formatted
text, hierarchically or otherwise structured. The big questions are: how
to store the formatting information (paragraph, heading, etc.) connected
to the vstream? How to store the other structure and make sure that
operations like cut&paste on the vstreams produce the right results with
the other structure.
