Comment 2 for bug 2033256

Is version_sort_sort_has_v missing initialization somewhere? https://git.launchpad.net/ubuntu/+source/grub2/tree/util/grub-mkconfig_lib.in?id=06f86533332124471075e20d139ceb97ce7a655b#n205

I initialized it to "yes" before calling the function version_sort and it generated the list.
