Yesterday on stackoverflow I accidentally edited someone's answer instead of my question.
I added an "Update: " and saved it then realized my mistake, and edited again, took that edit out and put it into the right spot (in my question).
But the edit that I made to the user's response still shows that I edited their answer, which might seem weird, when that user sees no differences.
So I think I might have missed out on a trick.
What if I want to completely UNDO (reverse) my own edit? I will of course hopefully be more careful in the future, but how do you revert your own edit and leave the question not showing "edited by me, 1 minute ago".
