Whenever you merge only some of the commits, you are actually
cherry-picking.  And cherry-picking is not tracked in the history DAG
of the VCS, at least not in bzr (and not in git, either).

You should merge without the -i switch, and without manually selecting
revisions to merge.  Then the meta-data will record all the revisions
you merged.  As Stefan says, using "M-x bzrmerge" is an easy way of
doing TRT in these situations (it will also pay attention to revisions
that were marked as "don't merge to trunk").
