Heh heh.

If you are at the URL:

   http://localhost:9017/demo/issue?@action=logout&...

and try to login you get logged out again as the __came_from
redirects to the logout action 8-).

I wonder if the login action should ignore a request to redirect
to @logout, or if I need to make the tal smarter to use
the base path if @logout is specified.

Suggestions?
