Custom Fields with "Link values to URL" set are displayed as escaped html in email
It looks like the function formatted_value in source:/trunk/lib/redmine/field_format.rb accepts a parameter html, but never uses it. Custom fields with a url pattern present are always returned as links.
Example Custom Field "External Link":
Name: External Link
Link values to URL:
Display in notification email:
External Link: <a href="https://support.example.com/tasks/26215">26215</a>
