ZPublisher.BeforeTraverse.NameCaller.__call__
can wrongly acquire "func_code".

This happens, e.g. for URLs of the form

	.../DTMLMethod/.../CMFPortal/...

The result is a 

2002-10-25T09:42:09 ERROR(200) BeforeTraverse Error while invoking hook: "cookie_authentication"
Traceback (innermost last):
  File /home/dieter/Haufe/src/Zope/lib/python/ZPublisher/BeforeTraverse.py, line 127, in __call__
TypeError: __call__() takes exactly 3 arguments (4 given)

The reason is "getattr(meth,'func_code',None)"
acquires the "func_code" of the DTMLMethod.
Therefore, the number of arguments is faulty.
