Fix SF bug #1458903 with AST compiler.

Browse source 
def foo((x)): was getting recognized as requiring tuple unpacking
which is not correct.

Add tests for this case and the proper way to unpack a tuple of one:
	def foo((x,)):

test_inpsect was incorrect before.  I'm not sure why it was passing,
but that has been corrected with a test for both functions above.
This means the test (and therefore inspect.getargspec()) are broken in 2.4.
