Detecting files that differ only in case being cloned onto a case-insensitive file system is a great feature. We recently ran into an issue when using the Nix build tool, which caches inputs based on a SHA hash, where it generated different hashes between Linux (w/ a case sensitive file system) and Mac (with a case insensitive one) machines.

Tracking that one down was pretty tricky. I didn't even consider that something at the Git level could be done to improve the situation!
