If your suspicion was that I did not really think it through, then you're 
correct. Of course, I would have transferred _all_ refs anyway, since the 
whole point of the exercise is to lose nothing.

However, I see where your argument is going.

Since Julian pointed out that there is a maildir patch for pine, I'll 
probably go for that one, since it is hanging lower.
