Post to Del.icio.us new window

The current Post to Del.icio.us link causes the post form to open in the current window or tab and then returns you to your previous page once you have submitted.
I prefer to still see the page I am adding so I have modified the java script.
(all one line !)

javascript:window.open
('http://del.icio.us/post?v=4;url='+encodeURIComponent(location.href)
+';title='+encodeURIComponent(document.title))()
