While I still think that it is more important to prevent such a
situation from occurring in the first place, ignoring .idx that lack
corresponding .pack should be fairly simple, perhaps like this.
Note that if we wanted to do this for real, I think such an ".idx"
file should also be added to the "garbage" list in the loop in which
the second hunk of the following patch appears.
