[Fedora-livecd-list] edit-lived for Fedora 13

[Marc Herbert]

This minor patch seems to make the recently committed (and
tremendously useful) "edit-lived" compatible with a vanilla Fedora 13
system (=livecd-tools release 31.fc12), and possibly earlier systems
as well.

Not really sure what should be done with it.
