<div class="block">Whether this setter is intrinsically multi-valued.

 <p>
 When parsing arguments (instead of options), intrinsically multi-valued setters consume
 all the remaining arguments. So, if the setter can store multiple values, 
 this method should return <code>true</code>.

 <p>
 This characteristics of a setter doesn't affect option parsing at all; any options can be
 specified multiple times.  In many cases, this is a no-op--but when your shell script expands
 multiple environment variables (each of which may contain options), tolerating such 
 redundant options can be useful.</div>
