post edit history would be nice

[divinity76]

when a post has been edited, there is no way to see the original text. would be nice if there was a way to see edit history.

for example StackOverflow.com implements edit history, if you go to https://stackoverflow.com/questions/1711631/improve-insert-per-second-performance-of-sqlite and click on the Edited-link it will take you to https://stackoverflow.com/posts/1711631/revisions where you can see all edits to that post. ("post revisions").
