Bad display of the previous version of a page while choosing the restoration date.

42 b7017

On the home page, I've entered some text, workflow validated, modified the text, workflow revalidated.
So, there are 3 steps in the page history:
step 1: no text
step 2: the original text
step 3 (current): the current text

When I choose the restore date from revision list, I can choose between the 3 steps previously mentioned. But it's useless to display the most recent version, because it's current version, and so there is nothing to restore if I choose this revision date.

In addition, when I click on the second date (wich correspond to step 2) to have a preview, the current content is displayed, and content wich will be modified by the restoration process is highlighted. But I can only see the current value wich will disapear, and not the previous value wich will be restored.
