Looks good!

I think this addresses <http://bugs.gnu.org/12827>, right?

Here the URI type is reused for URI references, which I think is good,
but could it introduce incompatibilities?  Like code that has expected
“normal” URI objects suddenly gets objects that are really URI
references.  (Just thinking out loud.)

Thanks for working on it!
