For user with right 'deletedhistory' but without 'undelete' the diff link on Special:DeletedContributions is useless. A click on it goes to Special:Undelete, and there is the diff link only in plain. It is better, when the user on Special:DeletedContributions see only a plain text and not a useless link.
The same for the timestamp (link to version).
Please rename 'restore' to 'view', because the user cannot restore the version, only see all (deleted) version of that page.
