If you have a tracked path a/b/c/d/e, and you changed your work tree to
make a/b to a symlink that points at a random directory, potentially
even outside work tree, that has c/d/e in it, we should not be fooled by
the fact that lstat("a/b/c/d/e") says "yup, the file exists".  As far as
git is concerned, that path does _not_ exist, as "a/b" is a symlink now.
