SVN rev 196962 on 2009-09-08 05:02:41Z by kientzle
Fiz /usr/bin/unzip: A bug deep in libarchive's read-ahead logic
(incorrect handling of zero-length reads before the copy buffer is
allocated) is masked by the iso9660 taster. Tar and cpio both enable
that taster so were protected from the bug; unzip is susceptible.
This both fixes the bug and updates the test harness to exercise
this case.
Submitted by: Ed Schouten diagnosed the bug and drafted a patch
MFC after: 7 days
