Not just randomly synchronize the revisions with no checks at all. This
is the way bazaar's UI does it.

Also, add a non-ff check.

This patch should probably go to maint, as the results of pushing the way we
currently push are not really understood. Perhaps it's similar to a 'git push
 --force', or perhaps it can potentially screw the repository.

It's better to be safe and just do what bazaar does.
