The first of these three results produces an incorrect relative path
because relpath does not strip off any non-directory tails before
comparing paths.
The start path is assumed to be a directory, which defaults to the
current working directory, and the input paths are first resolved as
absolute paths. In order to reach src_path from vcx_path, one has to
traverse 3 levels up to the root directory.

Well, it's not necessarily the optimal relative path, because it's not
always necessary to go all the way up to the root, as in the first example.
