incoming: show changed bookmarks in addition to new ones

Currently, `hg incoming -B` shows only new bookmarks on the server, not updated
bookmarks. This seems wrong -- I would expect it to show all bookmark activity.
Certainly, the help message of 'compare bookmarks' implies that this is what it
will do. Let's make `incoming -B` behave like it feels it should.
