[issue22102] Zipfile generates Zipfile error in zip with 0 total number of disk in Zip64 end of central directory locator

I also ran across this issue today, where the 'disks' value in a Zip file is 0. I'm trying to find out what software was used to create them, but it's quite plausible that it's Windows as Ramsey Kant suggests. So I think this fix should get applied to 3.8 and 3.7. Would it help if I produced a patch?

The PKWare Zip specification that takluyver links above has been updated -- it now has an April 29th updated -- but none of the changes are relevant to this.

Interestingly, the 'ditto' command on MacOS X (which can also unpack zip files) doesn't complain about the disk number either. I was unable to figure out where the source code for ditto is; I couldn't find it on opensource.apple.com.
