Note that I'm not the one who has this problem, but my understanding is
that it happens when the ~/.config/fish is somewhere under a Windows
junction, not a symlink.

It's true that the user could avoid the problem by changing their file
systems so that ~/.config/fish isn't under a junction point. But I don't
think they should have to do that.

To me it seems like a bug that rename2() is failing when the target file is
under a junction point.
