new List(size) constructor docs missing critical "this is not an expandable list" note

[sethladd]

Please add a doc comment for "new List(size)" that mentions that a List created this way is NOT expandable.

(I think there should be an explicit interface for ExpandableList, IMO, but that's another bug...)
