2005-07-14 Atsushi Enomoto <[EMAIL PROTECTED]>
* SimpleCollator.cs : rewrote IsSuffix() to use CompareInternal().
Thus supported extenders in IsSuffix().
* CompareInfoTest.cs : IsSuffix() extender tests got working.

* SimpleCollator.cs : more IsSuffix() simplification, but it will be
stopped here since it cannot handle extenders (implementing new
approach one).
