Deletion of git repo causes incorrect block count on HFS+ case-sensitive

Hello,

When I delete a git repo that I have cloned on my machine using 'rm -rf repo-name' I get an incorrect block count when I attempt a Disk Repair.

I am running OS X 10.8.2 on a user installed SSD. The git version is 1.8.1.5.
