You need more metainfo than the commit message. Since revision-id is
not based on the content, you need at least to specify the
revision-id.

And bzr's bundle give indeed _all_ the information that is in the
repository about this revision (i.e. commit message, ancestors, ...).

Another relevant difference between a patch and a bundle is that the
bundles knows its ancestor, so, when you apply the bundle, it builds
the new revision with exact patching. If you need a merge, then it
will happen exactly in the same way as a merge between two branches
(ie. three-way merge for example).

Not directly AFAIK, but since the bundle knows which revision it
applies to, it will refuse to apply the second if the first one is not
in your repository already for example.

It would probably be interesting to have more features to help sending
series of bundles and apply them, but no one have been really asking
for it up to now.
