Doesn't work for all cases?

[rmsutton]

I can see this [well written] implementation is based on Aoe1992 but it seems like it doesn't work for all cases.

var trie = new Trie({...});
trie.insert('baby#');
trie.insert('babe#');
var c1 = trie.contains("baby#");
var c2 = trie.contains("babe#");

I would expect c1 and c2 to both be true but c2 is false.

Have you experienced the same issue?
