 It would be great if the revision management functionality could include a
 way to preview any revision. From a quick look at the source code, wp-
 includes/revision.php declares a function called

 _set_preview($post)

 By default it loads the most recent autosave with:

 $preview = wp_get_post_autosave($post->ID);

 I would like to propose that that line be changed into:

 $preview =
 !empty($_GET['preview_id'])?get_post($_GET['preview_id']):wp_get_post_autosave($post->ID);

 The nonce has already been verified in _show_post_preview(), so there
 should be no security implications of this change.

 With this change, the Revisions meta box (Edit Post screen) could display
 a "preview" icon/link that includes the appropriate nonce and does the
 same thing as the main "Preview" button.
