Since Git enables Windows NTFS case sensitivity while checking out sources

I didn't know that. Would you give us a link to this feature?
As far as I know, `git config core.ignorecase` doesn't mean NTFS case
sensitive.

If a repo is cloned into a case-insensitive directory, then
core.ignorecase should be enabled automatically. If a repo is cloned
into a case-sensitive directory, then core.ignorecase should not be
enabled automatically.

I searched through relevant issues on the Git for Windows repo on
GitHub, and I found nothing to indicate that a capability to
automatically enable NTFS case sensitivity has been added. I searched
through the source of Git and Git for Windows, and I didn't find any
references to WinAPI SetFileInformationByHandle: FileCaseSensitiveInfo
or NTAPI NtSetInformationFile: FileCaseSensitiveInformation, nor the
use of fsutil file setCaseSensitiveInfo.

In this case: not sure what is going on. In a git-shell on Windows:
If caseSensitiveInfo is disabled:
user@host MINGW64 ~/K
$ fsutil file queryCaseSensitiveInfo .
Das Attribut für Groß-/Kleinschreibung für das Verzeichnis
"C:\Users\user\K" ist deaktiviert.

$ git config --global -l
core.ignorecase=true

$ git clone https://github.com/python/cpython.git

All directories created by git have caseSensitiveInfo enabled.

core.ignorecase is not regarded in any way. It does not mater if it is set or not.
