You might want to check out the ls-merge bzr command I added to
the lp:landscape-review plugin. It allows you to say (while standing in
the trunk branch) "bzr ls-merge <branch-to-merge>", and it will
automatically create such a message using the branch's merge proposal.
I.e. it will look for any bugs linked to the branch as well as who
reviewed the changes. It will also pre-fill the rest of the commit
message with the merge proposal's description, so you only have to write
what the branch does once. If you're interested in using it, I could
extract that command into a more general (not Landscape-specific) plugin
and give it a better name.
