Queries the user for values to return.
If the recovery protocol of condition allows returning values, this engages the program user in a dialog and returns the results as any number of values, which the handler should return.
return-query should not be called if return-allowed? returns #f. Programs that define condition classes whose recovery protocol allows returning values should ensure that there is an appropriate method for this function defined on or inherited by the condition class.
