[code-quality] Getting Flake8 to report syntax errors.

[Kannan Goundan]

Sample input file "test.py":

    def f(x)
        print x

Pyflakes reports the syntax error:

    $ pyflakes test.py
    test.py:1:9: invalid syntax
    def f(x)
            ^
    $

But Flake8 doesn't:

    $ flake8 test.py
    $

Is this intentional?  Is there a way to get Flake8 to report syntax errors?
