Question: When going through the edit queue, I saw 2 edit suggestions which included un-necessary edits.

The interesting thing is that these un-necessary edits weren't there to actually edit the post. they're there to get around arbitrary blockades that SO sets up. 

One to allow someone to undo their apparently incorrect downvote

If you want to prevent tactical downvoting, than you don't have to refund the voter's reputation if he decides to remove his downvote but would otherwise be blocked. 

and one to dance around the 6 char edit limit.

Some of the most common and most crucial mistakes that new(and sometimes even not so new) users make is not formatting code blocks. This problem can normally be fixed 100% by white-space. and when you encourage users to hunt for other things to change, you get results like in the example.

Answer: 
If you are not an amazing editor who pays attention to the detail it's hard to sit down for more than 2 minutes to check what other items are wrong or need editing with a post.

Yes, maybe, no, I don't know? Really, there is a whole community out there willing to check it. Why do I have to do 100% of the work?

*I saw something that needed fixing and I fixed it, let me bounce along with life and get on my merry way* and users want to bust my balls for something else? What happened to every contribution counts?

**Voting after edits**

This is a valid scenario. And since there is no way to even know when the post was edited or even get notifications (other than keeping a log of every question I downvoted and looking through them), I would do the same and have done the same in the past.

**Dancing the 6 char**

Why 6? Why not 7 ate 9? It's arbitrary unless there is some magic data sheet explaining the limit of triviality as chars approach 6 in some mathematical function.

Fine, I give up, I wouldn't edit it.

Maybe your original post does not convey what needs to be said to the popular meta fanatic, but below the surface there are deeper flaws in Stack Exchange working against providing contributions and natural user flows that is failing to be addressed such that all you can say about them are that they are...

arbitrary.
You're right, they need to fix those blockages to the system. It should be a clue when lots of people have to do workarounds to get common sense things done. Instead of trying to force people on a path that doesn't allow them to fix the things that need fixing, change the system to work with the behavior that is being used.
