AFAICS, the patch I just proposed handles this.

If I recall the code properly, we do not have to make canonicalize_path
remove embedded "." or ".." --- that is, we do not have to simplify

    /usr/local/../bin

But we do have to get rid of every trailing "." or "..", else there are
failure cases when we replace the trailing component with an ordinary
file name.
