Remove trailing "#" on rake routes for controller only routes

[htanata]

When running rake routes for controller only route like:

match 'api/:action' => 'api'

we get:

  api/:action(.:format) api#

This patch removes the trailing #.

I think "api#:action" would be a better result. It is more clear. What do you think?

[htanata]

Yes, it looks clearer. But then shouldn't we also apply it for the others for consistency? For example:

match ':controller/:action'
=>  /:controller/:action(.:format) :controller#:action

match ':controller(/:action(/:id))', :id => /\d+/
=>  /:controller(/:action(/:id))(.:format) :controller#:action {:id=>/\d+/}

In other words, we put :controller and :action where it's empty.

Yes, please.

I've updated my patch.
