I have created a RAR file containing two zip files like this:

zip bag.zip README.md CHANGELOG.md
zip bag1.zip CHANGELOG.md
rar a zips.rar bag.zip bag1.zip

And when calling `zipfile.is_zipfile` on zips.rar, it returns true even though it obviously is not a zip. The zips.rar file doesn't even begin with the magic bytes `PK` for zip but with `Rar!`.
