Well, I think there is an easy solution.

Just go back and say that when the user limits the size, it limits the 
offset at which objects can *start*.

Not only is that the only thing that the index file itself cares about, it 
also means that

 - you don't ever need to undo anything at all (because you know the 
   starting offset) when you begin packing a new object.

   This should simplify your patch a lot.

 - the object size issue just goes away. Sure, the pack-file limit looks a 
   bit strange (it's no longer a hard limit on the *size* of the 
   pack-file, just on the object offsets), but let's face it, we really 
   really don't care.

And in practice, by setting the pack-file limit to 2GB (or even 1GB), you 
never ever have to worry about the 32-bit filesystem limits any more, 
unless your repository is fundamentally so screwed that you simply 
*cannot* reporesent it well on something like FATFS (ie any object that is 
2GB in size will probably have a blob that is even bigger, and FATFS 
already has problems with it).

So in practice, just limiting the index offsets is what you really want 
anyway.
