I wanted to have the smallest footprint as possible in the objects 
directory, and the .git/objects directory currently only holds folders.

I suppose this feature, along with the multi-pack-index (MIDX), extends 
the concept of the pack directory to be a "compressed data" directory, 
but keeps the "pack" name to be compatible with earlier versions.

Another option is to create a .git/objects/graph directory instead, but 
then we need to worry about that directory being present.
