==================== Summary ====================

Name: System-ul.937
Author: ul

UUID: 01691bb8-181f-4795-83ce-20130031a81d
Ancestors: System-ul.936

Fixed SmalltalkImage >> #specialSelectors. SystemTracer doesn't use it any more, but it's being used by tests, which expect it to return only the selectors without their argument count.
