Created attachment 1761

correct zip file, which is handled wrong by std.zip

The attached zip file is a correct zip file according to the specification
https://pkware.cachefly.net/webdocs/APPNOTE/APPNOTE-6.3.5.TXT

It contains a zipped file called "best_language" with content "D". But std.zip
will output "FORTRAN" instead. (By the way, linux tool unzip is tricked too,
gunzip not. I havn't tried other programs yet.)

The file contains a file comment at the end. std.zip detects inside this
comment a central directory and therefore misses the correct central directory.
