Is this right?

I was in a meeting with Mark the other day, and he suggested pretty
much this, but for a slightly different use case.

If bzr remebered what the user asked for and what they got then when
a branch disappeared or diverged it could use tell the user some 
scenarios for what may have happened and ask them how they would like
to proceed.

I do not know what the UI for this would look like.

Also, there would be performance implications for some of the cases,
and to work out what was going on bzr would have to do the
equivalent of "missing" on an extra branch or two, just to flesh
out an error message.

Exploring some of the implications and trying to come up with a design
would be interesting though.

Thanks,
