pytest doesnt show doctest stdout when given -s

[Jon Crall]

Here is a MWE

"""
__file__ = mwe.py 
"""

def foo():
    """
    Example:
        >>> foo()
        >>> print('stuff')
    """
    print('bar')

if __name__ == '__main__':
    r"""
    CommandLine:
        python mwe.py foo
        pytest mwe.py::foo:0 -s
    """
    import xdoctest
    xdoctest.doctest_module(__file__)

Using the xdoctest runner stdout displays as normal
python mwe.py foo

Start doctest_module('mwe.py')
gathering tests
running 1 test(s)
============
* BEGIN DOCTEST : mwe.py::foo:0
bar
stuff
* SUCCESS: mwe.py::foo:0

But using the pytest mechanism nothing is shown
pytest mwe.py::foo:0 -s

Possible reason: verbose may not be passed down to the xdoctest DocTest.run method from the pytest plugin.
