Yes that's better but it reminds me of footnotes. This is all a visual thing.
(Personally, I really don't care if new windows open or not, so it seems a shame to spoil the beautiful layout with extras.)
It seems like it would be really easy to copy this effect programatically:
[a href="[link|http://www.whitehouse.gov"]Whi[/a][a|http://www.whitehouse.gov"]Whi[/a][a] href="[link|http://www.whitehouse.gov"|http://www.whitehouse.gov"] target="[link|http://www.whitehouse.gov"]te[/a]|http://www.whitehouse.gov"]te[/a]] House
(mentally remove the munging - the second part would be targeted.)
