Like access to more detailed event information

Currently, when a node is modified twice within the notification interval, we can create the following message:

Updates for [node type]: [title]
- The [node type] has been updated.
- The [node type] has been updated.
Read more [node-url]

We would like to access more of the detailed node revision and/or event information when nodes are updated. The dblog module's report has detailed information for the event, including the acting user and a timestamp; however, I don't see how to capture this information in the messaging module.

Updates for [node type]: [title]
- The [node type] has been updated by "user A" at 12:00...
- The [node type] has been updated by "user B" at 12:05...

What are we missing? Many thanks.
