Yes, patching zipfile is enough. I wrote a test using `unzip -t` to check the
zip. ZipFile.testzip can't detect this kind of error because

I think there is another problem. The docs of `untokenize` said The iterable
must return sequences with **at least** two elements, the token type and the
token string. Any additional sequence elements
New submission from Dingyuan Wang:
If a script uses tabs for indentation, tokenize.untokenize won't restore

and thus breaks the file.
This affects all Python versions.
