    [options] bugfix don't override inbuilt list keyword
    
    fixing a 17 year old bug.
    
    previous version had defined (save-acc list count) and (save-item list
    count) thereby overwriting the inbuilt 'list' keyword, and tried to use
    the it later on with (list key)... best rewrite with neater code.
