Is _wgetcwd the right choice here? Shouldn't this instead go straight to Windows with GetCurrentDirectoryW so it doesn't take a dependence on MSVC's CRT?

I guess we could do that as well; we still have a few other calls that go through the CRT (in the FileDescriptor helper class further up in the file, used for file copying), and in this case, there's no other practical limitation in _wgetcwd that we'd get around, other than cleanliness. (Calling GetCurrentDirectoryW takes two calls and manual allocation inbetween, unless we want to hardcode a PATH_MAX allocation, but I'd rather move away from such specific limits.)

But yeah I can change it if you still prefer that.
