OK.  This array is used in cmd_repack() to call rename() in the
order in which its elements appear, so moving the entry to the last
means it will be renamed the last.

And the .idx entry MUST stay the last.  I wonder if dropping the
trailing comma and replace it with a "/* must be at the end */"
comment would be an effective way to ensure that.
