Hyperlinks should depends on path elements

[nojhan]

After PR #668, path elements are linked toward $PWD, because only the path label is passed to _lp_create_link_path, but ideally, the absolute path down to the current label would be passed, so that we can build up a link to this specific directory. However, _lp_path_format being such a complex function, I am not at ease at adding such a feature there.
