// Some zip files can contain garbage after the comment. For example, python zipfile generates

// it when opening a zip in 'a' mode:

//

// >>> from zipfile import ZipFile

// >>> with ZipFile('comment_garbage.zip', 'a') as z:

// ...     z.comment = b'long comment bla bla bla'

// ...

// >>> with ZipFile('comment_garbage.zip', 'a') as z:

// ...     z.comment = b'short.'

// ...

// >>>
