Steps to reproduce

• Create a content
• Modify it several times
• Archive it
• Restore it
• Modify it several times
• Restore a version before the archiving

You should obtain something like this:

Problems
The versions are 1, 2, 3, 4 then again 1, 2, 3, 4.
The comment only talk about a "version 2", so it is incomplete.

Possible solutions
Maybe we need to always display the full version number.
Maybe we should add the version date to the comment (even if it is not user-friendly because of intermediate versions).
