 In XHTML, link tags in the HTML head need to be closed:

     <link title="test" href="http://example.org/test"/>

 Wordpress' oEmbed discovery in `WP_oEmbed::discover()` fails on this.
 It extracts the attributes (` title="test"
 href="http://example.org/test"/`) and sends it through
 `shortcode_parse_atts`. The trailing slash is included even though it's
 not part of the attributes.

 Either `discover()`'s link tag should not match the slash, or
 `shortcode_parse_atts` should be changed to cope with it.
