Seeing this definitely makes me think this should be reported to the Git for Windows project (https://github.com/git-for-windows/git) because that's a nonstandard option that's specific to Windows. I don't think anyone here (other, of course, than the Git for Windows folks) is familiar with how that option works and since it isn't part of core Git we wouldn't be able to fix it.
