My understanding is that the histories of some of the branches we have
now are flat-out wrong.  I don't have a problem keeping those
alongside the corrected history for ease of rebasing and porting
commits, but I don't want to punt the problem of figuring out what the
one, true, and correct history is to the user.  The canonical
repository needs to provide that, and if it provides other alternative
timelines (a la Star Trek) for the convenience of people in Heikki's
situation, that's OK too, as long as they are clearly labeled as such.I think ideally we'd phase those out and garbage
collectthem 
eventually, but we can certainly keep them for a while.
