I just `git add`ed a 100MB file to a test repo, and `.git/index` only grew to 104 bytes. So it seems to only contain metadata. TIL.

  And if you go dig into `objects/`, you'll find your (possibly compressed) 100 MB object under its hash, and can view it with "git cat-file -p $hash" without ever having committed it :) Edit: And I bet if you dig around your index file enough, you'll find that hash someplace in there.
