Summary: Patch to zipfile.py for Java
Initial Comment:
This is an alternative to the zipfile.py patch 442128
by Finn Bock (bckfnn). Java fails to read zip files
created by zipfile.py because it requires a 4 byte
header for the CRC and file sizes which are written
after the file data, and the zip specification does not
have this header.
This patch will unset flag 0x08 (flags will be zero) to
indicate the CRC and file sizes do NOT follow the file
data, and will seek() backwards to write them in the
file header. This is consistent with the zip format
and eliminates the problem with Java. The patch has
been tested with WinZip.exe on Windows, is very simple,
and hopefully will make it into 2.2.

Zipfiles created by this patch can also read by java and
the solution is far better than #442128.
Checking in zipfile.py revision: 1.16;
