There are a number of places where you want to find all the objects
which reference this particular object. AIUI this is not currently an easy
task. Some thought should be put into how to make these reverse
lookups fast.

I have.  Please look at my old postings.  It turns out to be easy;
just create a directory parallel to .git/objects, say:
   .git/reverse
      00/
        89123408312904819048390/
           189412890892308290
           238923849038329089

Anyway you get the idea.

Seems reasonable.

Linus does NOT want renames noted; see the old emails on that.
It's not clear this is such a good idea, but he's adamant.
He thinks this can be handled by merge.
If not, it can be added later.

I realize that this is not a priority for linus,  I was suggesting that
it be added as a separate object type.  I think that many of the
extra metadata could be usefully added as other object types.
These can be optional and/or added after the fact.
