Comment:

 @adamsilverstein I tested the patch. I follow below steps.

 1. Create new post with title and content
 2. Save post.
 3. Click on Preview button (Multiple time) it return "There is nothing to
 save. The autosave and the post content are the same." with no revision
 create.
 4. Update content
 5. Click on Preview button (Multiple time) it save the revision.
 6. Again update some content
 7. Click on Preview button (Multiple time) it save the this new revision
 and remove previous revision.
 8. Again update some content
 9. Click on Preview button (Multiple time) it save the this new revision
 and remove previous revision.

 Is it valid? Do you think we have to save that revision?
