Link construct uses link text rather than link target when link text 'looks' like a URL

I don't know if this is a bug, or the intended behaviour.

If I create a link in XWiki syntax 2.0 like this;

[[http://www.google.com>>http://www.yahoo.com]]

The link is actually to http://www.google.com not to the link target, http://www.yahoo.com.

If the http:// prefix is removed, like this;

[[www.google.com>>http://www.yahoo.com]]

then the link is to yahoo, as expected.

I guess it may be a like this to help prevent phishing, but I noticed it while migrating ~8000 page from another system into XWiki. I remap links to the new target, but those which use the URL as the link text still point to the old target, despite following the syntax correctly.
