Redmine

There are 2 email views

+ test_email.html.erb
+ test_email.text.erb

having no localized text:

# test_email.html.erb
<p>This is a test email sent by Redmine.<br />
Redmine URL: <%= link_to @url, @url %></p>

# test_email.text.erb
This is a test email sent by Redmine.
Redmine URL: <%= @url %>

Supporting a translated text also for test email is only little effort but would improve consistency and user experience.
