Comment (by mintindeed):

 You'd probably want to exclude some post meta that are specific to the
 main post, like edit locks.  I imagine the patch would look something like
 this:


 {{{
 $exclude_meta_keys = apply_filters( 'revision_meta_do_not_copy', array(
         '_encloseme',
         '_pingme',
         '_edit_last',
         '_edit_lock'
 ) );
 $current_meta = get_post_custom( $GLOBALS['post'] );
 if ( is_array( $current_meta ) ) {
         foreach ( $current_meta as $meta_key => $meta_value ) {
                 if ( in_array( $meta_key, $exclude_meta_keys ) ) {
                         continue;
                 }

                 update_post_meta( $revision_id, $meta_key, $meta_value );
         }
 }

 }}}
