When I recently experienced an edit collision, I got the (new and improved!) text:
This post has been edited 1 time since you began. Your edit can only be saved if it is more thorough than the currently saved edit.
How do I determine if my edit is "more thorough"? Does the system do that magically? (There's a lot of amazing magic here. :) Or am I supposed to gauge "more thorough"? How? I can't easily see the new text and my text side-by-side. Or did I miss how?
