Why don't git-init and git-clone probe for core.ignorecase on Windows > XP?

Hello.

The git-config manpage says about core.ignorecase:

"The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created."

I assume this is happening when you clone or init on FAT, which is explicitly mentioned earlier in that section. But apparently it doesn't happen for either XP, Vista or 7. While those newer releases use NTFS, which technically supports case-sensitivity, the operating itself still apparently doesn't, so it would seem like git-clone and git-init should probe regarding the core.ignorecase on any version of Windows, no?

Thanks, D
