Problem: In Russian Wikipedia I've found that most translations made before translation tool introduction doesn't have enough attribution in their edit summaries (or doesn't have it at all), because local rules allowed talk page template instead of attribution in edit history. There is no technical mechanism for attribution repair in the Wikipedia. Dummy edits are not official repair mechanism but are the only way to mark an edit as translation in edits history. Dummy edits are useless in long histories because search for added text won't show dummy edits near real edits without attribution in their summaries. Also they might vary in form and format. If somebody want to find out the source of the edit without attribution he will find added text and might try to add dummy edit. If another user already fixed attribution, duplicates may appear.
Proposed solution: Administrators or patrollers need to have technical possibility to link one edit to another if edit summary have special tag inside it and a reference to the original edit using special:redirect/revision/XXXX link. Linked dummy edit summary should appear near real edit summary in the page history and other tools. Alternatively comments to edit summary may be more appropriate feature, but their usage must be limited to forbid chatting.
Who would benefit: It might help to repair many Wikipedia articles in legal terms and prevent from adding attribution multiple times. Also it may be useful in some other cases like fixing previous edit summary.
