But automatic replacement is not possible, because `"\n" != r"\n"`. But I
checked carefully that all changed places with `\n` and `\t` are regexps, and
in regexps it is semantically the same.
```
>>> '\n' in 'test \n test'
True
>>> r'\n' in 'test \n test'
False
>>> import re
>>> re.search('\n', 'test \n test')
<re.Match object; span=(5, 6), match='\n'>
>>> re.search(r'\n', 'test \n test')
<re.Match object; span=(5, 6), match='\n'>
```
