Bah!  That's a bug.

I had it use "(uncaught-exception-handler)" but the parens were
accidentally lost when I edited it to be a link to the toplevel
page...  I'll fix that.

(I preferred that over `raise' because the 404 page is more of a
toplevel exception thing than a catchable exception, and because the
name makes the page look more like an error.)

Suggesting an alternative URL would be very nice, but there's no easy
way that I know of to do that.  (Note that I also avoided making it
redirect to the top page after a delay, since that's probably more
