documentation:

--- Complete all partial case branches occurring in the body of a function
--- by adding `Prelude.failed` branches. The first argument contains all data
--- constructors grouped by their data type. If the second argument is `True`,
--- only a single branch with an anonymous pattern is added (if necessary),
--- otherwise branches for all missing patterns are added.
