pd_defaultlist looks at the content of the list. if the size is 0 and 
there is a nondefault bangmethod, it is called. if the size is 1 and there 
is a matching floatmethod, symbolmethod or pointermethod, it is called. 
otherwise, it will be auto-unpacked and distributed to inlets, unless the 
object is a «nonpatchable» (that is, it's a DS).

The message class defines a method 'list', and because of that, a 'list' 
selector would naturally stay 'list'.
