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
