Comment 4 for bug 439640

Hit the same today. I had this branch:
https://code.launchpad.net/~mysql/mysql-server/mysql-next-mr-bugfixing
at revision <email address hidden>.
I did "bzr pull -v" from the parent, which fetched up to <email address hidden>.
I saw removed revisions like this:

1) it's confusing as a "pull", unless it has "--overwrite", shouldn't remove anything, only possibly add revisions and renumber revisions.
2) actually the revision above was not removed, it's still present after "pull" completes.
So I have the same comment as Daniel: I don't understand what the message means and don't see a possible wording for it.
