When adding a fileobj that is not seekable to a zip using the zipfile module, the optional signature value 0x08074b50 is not included. This breaks certain zip implementations, including the builtin MacOS Archive Utility. See https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT sections 4.3.9.3 and 4.3.9.4 | |||

Thank you for your contribution Silas. Since popular ZIP file implementation like Info-ZIP and Java write this signature unconditionally, I think most unzipping software support it if they support reading ZIP files in streaming mode at all, at it is safe to backport this change to all maintained versions. | |||
