This is sadly nothing we can change because Windows' permission system is so vastly different from Unix' simplistic permission model (and honestly, Windows' ACLs are quite a bit more powerful).

In any case, this feature would have to be addressed by the Cygwin project, because the underlying POSIX emulation layer is implemented in the Cygwin runtime (which Git for Windows uses in the form of the MSYS2 runtime).

If you want to report this with the Cygwin project, please use this link.
