I think this is auto-generated.

A patch back in May 3 changed grub.d/00_header.in.

   revno: 4969
   committer: Andrey Borzenkov <arvidjaar@xxxxxxxxx>
   branch nick: trunk
   timestamp: Mon 2013-05-06 22:13:34 +0400
   message:
         Reimplement grub-reboot to not depend on saved_entry. Use
         next_entry variable for one time boot menu entry.


What surprises me is that Fedora 19 picked up the change so quickly...
