Yah, I'm not sure that's a bug, exactly. The help file originally was written to show the bottom case. It then got changed a few hours ago to include the  bit. So I think this might be a case of the instructions being wrong, more than a true bug. I'm not entirely sure, though: there might be some reason that it's important that the  bit be included. But since leaving it off does effectively get you to the right wiki, I'm not sure why the  actually is important — other than the fact that we're used to including the   in simple interwiki linkage.
