But I have experienced the same earlier with some other post-1.5.5 version so I believe you can reproduce this yourself. After cloning Linus's linux-2.6 repo its .git directory weights 209MB. After single "git pull" and "git gc" it was 298MB in my test.
I noticed that a while ago: when repacking multiple packs when one has a .keep file, the resulting additional pack contains too many blobs and trees, contrary to when only packing loose objects: $ git init $ echo a > a; git add a; git commit -m a $ git gc Counting objects: 3, done. Writing objects: 100% (3/3), done.
