The problem here is that file:///usr/share/debian-reference doesn't
exist.  But if you run url-retrieve on that, the URL library helpfully
roots around in that directory to see whether it can find a likely file
to display instead, and it finds
file:///usr/share/debian-reference/index.html.  But it doesn't report
this back to eww in any way, so eww thinks that the document is
file:///usr/share/debian-reference, and so all the references are wrong.

I don't really know what to do about this corner case...
