+Everybody loves URL shorteners. These are some options for fine-tuning
+how and when the server shortens URLs.
+
+shortener: URL shortening service to use by default. Users can override
+ individually. 'ur1.ca' by default.
+maxlength: If an URL is strictly longer than this limit, it will be
+ shortened. Note that the URL shortener service may return an
+ URL longer than this limit. Defaults to 25. Users can
+ override. If set to 0, all URLs will be shortened.
+maxnoticelength: If a notice is strictly longer than this limit, all
+ URLs in the notice will be shortened. Users can override.
+ -1 means the text limit for notices.
