When run test with docstring, FAILURE message indent is unexpected.

For example,

import unittest
class TestSome(unittest.TestCase):

    def test_bar(self):
        """
        This test fails.
        """
        self.assertEqual(1, 3)

run above test with pytest, following message is shown.

    def test_foo(self):
        """
            This test fails.
            """
>       self.assertEqual(1, 3)
E       AssertionError: 1 != 3

But I expected message like below.

    def test_foo(self):
        """
        This test fails.
        """
>       self.assertEqual(1, 3)
E       AssertionError: 1 != 3

I found out the cause is probably tokenize.generate_tokens. (It is used src/_pytest/_code/source.deindent ). However, I do not know how to fix it.
