annotate 2.7.2 adds trailing space to the last line of route map

[monad-san]

After updating annotate gem to 2.7.2, when I run annotate --routes in rails project, it adds a trailing space to the last line of config/routes.rb route map.

expected result (< 2.7.1):

# == Route Map
#
#                   Prefix Verb   URI Pattern                                 Controller#Action
#                     root GET    /                                           hoge#index
(... routes lines ...)
#[EOL]

actual result (2.7.2):

# == Route Map
#
#                   Prefix Verb   URI Pattern                                 Controller#Action
#                     root GET    /                                           hoge#index
(... routes lines ...)
# [EOL]

Rubocop (Layout/TrailingWhitespace) detects it as offense.

How did that happen? I thought we had unit tests? Wait...
