It's not that I am not interested in fixing it. It's more like I hoped that I could work on Git for Windows v2.20.0-rc0 and rely on you to fix this bug.

Now that Git for Windows v2.20.0-rc0 is out (see https://github.com/git-for-windows/git/releases/tag/v2.20.0-rc0.windows.1), expect a patch soon (see https://github.com/gitgitgadget/git/pull/86).

Ciao, Dscho
