Re: [PATCH 2/4] archive-zip: remove unneccesarry condition in write_zip_entry()

> The function write_or_die() can handle a length that's zero, thus we can
> remove the condition that checks the value of `out_len` that surrounds
> this call. The value shall never be negative as this would have caused
> data being omitted in the deflated output.
