The current operations column in the revisions overview page assumes that there will always be 2 operations and only 2 operations (unless it is the current revision where there is none). This makes it difficult for other modules to extend the functionality of this page. I understand this inherited from revisions overview form from node.module. I don't think this needs to be retained. I propose that the arbitrary assumptions in the module be dropped in favour of a more flexible approach.
The attached patch resolves this problem.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Given the proximity of EOL for Drupal 7, marking this as won't fix. The likely final Drupal 7 release of diff has landed in https://www.drupal.org/project/diff/releases/7.x-3.5 → . If this is something still applicable to a more modern version of the module, feel free to re-open and post additional notes.
