# Query string parameters will get escaped.

# Example:
# url_for_pattern("/:controller/:action/:id", {:controller => :blog, :action => :show, :id => 1})
# # => "/blog/show/1
# url_for_pattern("/:controller/:action/:id", {:controller => :blog, :action => :show})
# # => "/blog/show/:id"
# url_for_pattern("/blog/:id", {:id => 1})
# # => "/blog/1
# url_for_pattern("/blog/:id", {:id => 1, :n_id => 2})
# # => "/blog/1?n_id=2
