Yeah but we're talking about .zip here. The member files within a zip
archive are compressed individually. That's why .tar.gz, which uses
the same compression algorithm, produces slightly smaller files.
(OTOH, because of this, zip archives are random-access, and it's
possible to recover files stored *after* a point of file corruption.)
