The only changes visible at the AST level, checked using https://github.com/asottile/astpretty, are zerver/lib/test_fixtures.py: '\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m' '\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n' which is fine because re treats '\\x1b' and '\\n' the same way as '\x1b' and '\n'.
