Fallthrough

[Rich-Harris]

page.js has a fallthrough mechanism, which does two things - it allows separation of concerns...

// `load` is passed a `next` function, which it calls once the user is loaded
page('/user/*', load);

// for both of these routes, the user will be loaded before the route handler is called
page('/user/:user', show);
page('/user/:user/edit', edit);

...and a way to handle routes that don't match anything:

page('*', function(){
  $('body').text('Not found!');
});

Would be neat to have something similar in roadtrip eventually.
