The following description uses bound branches, presumably it works in
a similar way with unbound ones.
-0) (First time only) Get the bzr changelog_merge plugin
-(this will be included by default in bzr 2.4 onwards):
+0) (This step is only necessary if using bzr older than 2.4.0.)
+Get the bzr changelog_merge plugin:
cd ~/.bazaar/plugins
-bzr branch http://bazaar.launchpad.net/~spiv/bzr-changelog-merge/trunk
-mv trunk changelog_merge
-
-This should make merging ChangeLogs smoother. It merges new entries
-to the top of the file, rather than trying to fit them in mid-way
-through. Newer versions of the plugin should also be able to deal
-with changes to *old* ChangeLog entries, that should not be floated to
-the head of the file (see launchpad#723968).

+It is included in bzr from 2.4.0 onwards, so remember to delete the
+copy in ~/.bazaar if you upgrade bzr.
Maybe the default Emacs behavior without this plugin is better,
though, it's not clear yet.
