Subject: [PATCH 1/2] Fix multi-method routes to append '(.:format)' only once

Because the same path string is used for each loop when the routes
are being built, appending the string using `<<` modifies the original,
causing multiple '(.:format)' strings to be appended. This fixes the
behavior, resulting in the proper path output.
