Did we silently drop Vista support? I thought we still officially supported it...

Seems as if this could be the same issue as https://github.com/GitCredentialManager/git-credential-manager/issues/576. If it is, then https://github.com/git-for-windows/git-sdk-64/blob/b66f658faf70ae7de7656c46973d3b371dea1ab4/usr/bin/msys-2.0.dll should work around the issue, and https://github.com/git-for-windows/git-sdk-64/blob/b66f658faf70ae7de7656c46973d3b371dea1ab4%5E/usr/bin/msys-2.0.dll should not. @brechtsanders could you verify this...

Try replacing your `msys-2.0.dll` with [Git for Windows' version](https://github.com/git-for-windows/git-sdk-64/blob/HEAD/usr/bin/msys-2.0.dll).

@brechtsanders then try with regular Cygwin. It's possible that it's a Cygwin issue, in which case they're usually pretty quick to fix 'em.

I believe that that's not the correct place, https://github.com/msys2/msys2-runtime/blob/b671a59da80fa1db6115e3275149f9639681453a/winsup/cygwin/path.cc#L2297-L2366 should be the correct one. But I am seeing `CopyFile()` being called with wide-character strings...

I am _really_ concerned about a change like this. It is _prone_ to break existing setups. Look e.g. at the lengths Git for Windows goes to quote things accurately for...
