         However, this is not often not desirable when piping output into other

         Formatted output is triggered by the value of the `ui.formatted'
         configuration variable or - if it is unset - when `sys.stdout' points

         considered an implementation detail; it is not intended for use outside
         Mercurial or its extensions.
