[publican-list] ulinks failing when not using the full "http://www" URL.

[Murray McAllister]

<ulink url="google.com" />

Tries to open "/home/mmcallis/test/testing/tmp/en-US/html/google.com."

...Maybe this one should not work, but I would have expected the 
following to:

<ulink url="www.google.com" />

Tries to open "/home/mmcallis/test/testing/tmp/en-US/html/www.google.com"

I don't remember this being how things always were, but my memory is not 
very good anymore :)
