Redmine

Currently, most locales define translations for Array#to_sentence using sentence_connector and skip_last_comma. However, these keys were replaced in Rails 2.3 (Release note) by last_word_connector, two_words_connector, and words_connector.

This patch updates the old keys to the new ones so that Array#to_sentence works as expected. The changes follow these rules:

• Values for the new keys are taken from the rails-i18n gem's locale settings .
• Locales that already define the new keys are left unchanged.
• zh (zh-CN) is aligned with the zh-TW settings.

Redmine currently does not use Array#to_sentence, so this patch should not affect any functionality or UI. However, some third-party plugins might use it.

I confirmed that all tests, including system tests, pass after applying this patch. Here’s how Array#to_sentence behaves with the updated translations:

$ bin/rails console
redmine-app(dev)> array = ['Redmine', 'Ruby', 'Rails', 'ルビー', '紅寶石']
=> ["Redmine", "Ruby", "Rails", "ルビー", "紅寶石"]
redmine-app(dev)> array.to_sentence(locale: :en)
=> "Redmine, Ruby, Rails, ルビー, and 紅寶石" 
redmine-app(dev)> array.to_sentence(locale: :ja)
=> "Redmine、Ruby、Rails、ルビー、紅寶石" 
redmine-app(dev)> array.to_sentence(locale: :zh)
=> "Redmine, Ruby, Rails, ルビー, 和 紅寶石"
