Issue#2238: some syntax errors from *args or **kwargs expressions
would give bogus error messages, because of untested exceptions::
>>> f(**g(1=2))
XXX undetected error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
instead of the expected SyntaxError: keyword can't be an expression
Will backport.
