As a user without full editing permission, I can not do a roll-back myself. Instead, I need to have the rollback reviewed by selecting a previous revision and suggesting that as edit.
I was wondering how such a suggested edit is shown to the reviewers: Is it obvious to the reviewers that my suggested edit is based on a previous revision (or do I need to put this into the comment)? Can the reviewers easily see what I changed compared to the base revision, or is the suggested edit always shown as diff to the latest revision?
The background of this question is the following: In a question of the type "What does this error message mean", the original poster added a word in error message in question: That either meant that he changed his setup compared to the original question (making it a different question), or that he was randomly editing the error message (making the question invalid). I wanted to revert this edit, so I chose the second last revision, explained the change in the comment, and proposed it. The change was rejected as too minor - which made me think that the reviewers didn't realize that the change was a rollback, but instead saw it as me wanting to remove a single word in the question. This is why I'm asking this question here.
