Oh, thanks for reminding me.  I had forgotten that Linus added -r
when someone else had corruption in a packed object.  Yea, if you
use -r it may be able to resume and pick up where it left off.

I haven't studied the -r code so I'm not sure how it knows where
its safe to restart unpacking from.  But if you have a .idx file
we probably could make a really good guess based on the offsets
it stores.  I doubt unpack-objects makes use of the .idx.
