2017-11-09unzip: fix content listing and filtering when -j is usedEugene Rudoy
Original Info-ZIP's unzip uses unstripped filenames while doing content listing and filtering, i.e. - in content listing mode -j is ignored completely - filtering is applied to non-stripped names, -j takes effect first while extracting the files 997ad2c64abbe931dffa3598b015c5de04e515cf strips path components a little bit too early resulting in behavior deviations.
