Nicolas Cellier uploaded a new version of Multilingual to project The Trunk:
http://source.squeak.org/trunk/Multilingual-nice.51.mcz
==================== Summary ====================
Name: Multilingual-nice.51
Author: nice
Time: 5 October 2009, 10:21:53 am
UUID: 78ba4a93-7c85-4f66-bc9d-a74ea3a97e41
Ancestors: Multilingual-nice.50
Fix http://bugs.squeak.org/view.php?id=6450
Let MultiCharacterScanner honour the stops argument rather than using stopConditions instVar.
