Currently, non-existant ancestors of a subpage are omitted.
They should be displayed as a red link.

Example: if only components 1, 3 and 5 of A/B/C/D/E exist, that
page is now shown as:

A/B/C/D/E
------------
< A · C · E

But it should be:

A/B/C/D/E
-----------
< A · B · C · D · E

(with B and D as red links).

And if none of the components exist, the path won't be shown at all.

Thanks.
