+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.
