Re: Fix object re-hashing

Btw, if it does trigger, the behaviour would be that a subsequent object 
lookup will fail, because the last old slot would be NULL, and a few 
entries following it (likely just a couple - never mind that the event 
triggering in the first place is probably fairly rare) wouldn't have 
gotten re-hashed down.

As a result, we'd allocate a new object, and have _two_ "struct object"s 
that describe the same real object. I don't know what would get upset, but 
git-fsck-index certainly would be (one of them would likely be marked 
unreachable, because lookup wouldn't find it, but you might have other 
issues too).
