Bug: [self.assert(x in y)]

[spagh-eddie]

MRE:

import unittest

class MyTest(unittest.TestCase):
    def test_mre(self):
        """docstring"""
        [self.assertTrue(0 in ())]

$ teyit test.py 
Traceback (most recent call last):
  ...
  File "<unknown>", line 7
    self.assertIn(0, ())
IndentationError: unexpected indent
Failed to refactor file 'test.py'

This is due to the first pass of rewrite_source() turning the line into ' self.assertIn(0, ())\n', indented by 9 spaces. I would instead expect it to output valid python.

teyit/teyit.py

Line 297 in 4ca1d27

source, _refactors = rewrite_source(source, blacklist=blacklist)
