In openSUSE 12.3, Grub2 is unable to correctly interpret the (very recently added) first line in openSUSE-13.1-RC1's /etc/SuSE-release. It ignores the #-mark and uses the entire first line as a descriptor of the release.
This problem did not occur in oS13,1-beta1. This results in a non-informative entry in the Grub2 boot menu in openSUSE 12.3 (and, presumably, but not tested, also in earlier versions.)

Reproducible: Always

Steps to Reproduce:
1.install openSUSE-13.1-RC1 in its own partition
2.boot and select openSUSE 12.3 (the "production system")
3.in oS12.3: run Grub2-mkconfig (and notice the nonsense id for oS13.1, run Gru2-install.
4. reboot and see the noon-informative text in the entry for oS13.1.
