Can be used to retrieve a list of parent paths, useful for searching ancestors recursively via their absolute paths. Paths are returned from deepest to shallowest, starting from the path passed in. Paths are not validated for performance reasons. (Usually the input to __fish_parent_directories would be (pwd) or (dir $file).)
