diffs: cleanup of variable naming around cut_off_limit A brief summary of this area: The base controller sets self.cut_off_limit from config and is used for diffs, unless controllers are given a fulldiff query parameter. In a few cases, these are passed to templates as c.cut_off_limit or c.fulldiff . Also, if the diff function returns a LimitedDiffContainer, c.limited_diff is set so the UI can report the data set is partial.
