Report on push/pull if heads are merged, too, like for new heads. Use case: If a remote repo has two heads and I _want_ to merge them, I merge and push. Meanwhile someone else pushed on top of one of the heads. He won't get a warning, because he doesn't create a new head, I won't notice that I don't close a head, because I don't get a message telling me.
