Unable to handle Urls for not-pluralizeable Resources

If the name of a Resource is the same as for singular and plural rails url-helpers seem to have trouble generating the appropriate urls.

I found some old (Trac) Tickets, but there never seems to have been a sollution.

Simple Example "News"

news_path(news) # works fine
news_path # does not work, singular helper but we want it to be index

simple fix for that would be

def news_path(news = nil)
  return news_index_path if news.nil? || news.new_record?
  super
end

If that sounds like a proper way to be added to the core i'd take this as a chance to submit my first patch.
