Comment (by stephdau):

 So yes, I think we should deal with this inside `get_canonical_link()`
 instead, especially since it itself uses alternative data keys if a
 canonical link isn't available, some which might have the same symptoms.

 I'd do with something along the lines of [attachment:31645-make-fully-
 qualified.diff], and then make sure that whatever uses
 `get_canonical_link()` tests for en empty return (which we should have
 anyways, if we did not yet).

 My patch doesn't process blah.html, or ../blah.html, etc. Just /blah and
 //blah.com/blah, but simply for the sake of giving a simple example. It
 could.
