merge: respect bookmarks during merge...
merge: respect bookmarks during merge Bookmarks will behave more like named branches when merge tries to pick a revision to merge. Bookmarks now to respect the current bookmarks. Bookmarks will not accidentally merged with unnamed heads or other bookmarks. However merge can pick heads with diverging bookmarks and pick those automatically. We end up with two cases for picking a revision to merge: (1) In case of an current bookmark, merge can pick a branch head that has a diverged bookmark (2) In case of no current bookmark, merge can pick a branch head that does not have a bookmark.
