[issue7362] Incorrect error message with def((x)=0)

[James Lingard]

New submission from James Lingard <jchl at aristanetworks.com>:

def f((x)=0): pass

gives the following incorrect error message:

  SyntaxError: non-default argument follows default argument

"def f((x)): pass" is treated exactly the same as "def f(x): pass", so
it would seem sensible for the same to be true if a default value is
used.  But if this syntax is disallowed for some reason, the error
message should be fixed.

This appears to be related to bug #1557232.

[Tested on Python 2.6 (r26:66714, Jun  8 2009, 16:07:29).]
