BTW I have code for an index version 2 that allows for 64-bit offsets.  
It also adds a CRC32 for each object data as stored in the pack to make 
data reuse safer when repacking.  I only have to fix a couple loose ends 
before sending patches out.

The new index only uses 64-bit offsets when it has to.  Meaning that 
objects in front of a pack which usually are the most recent ones won't 
pay the overhead of a larger offset table at run time.
