+ *   - "view": The comment is being viewed. This hook can be used to add additional data to the comment before theming.
+ *   - "validate": The user has just finished editing the comment and is
+ *     trying to preview or submit it. This hook can be used to check or
+ *     even modify the node. Errors should be set with form_set_error().

+ *   - "unpublish": The comment is being unpublished by the moderator.
