Ah! Thanks for the list. Now that I'm back
from vacation, I've been meaning to ask you
for that.

I still have a faint hope that we can support this without
the changes DES is proposing, but he's probably right.
(In particular, I would like to be able to extract
SFX archives from stdin, which requires that we avoid
seeking.)
I hope to do some experiments in the next few days
to see if I can come up with anything. Though by
then, DES may well have demonstrated that his
approach isn't as complicated as I thought.

I just committed a fix for this. PK00 is documented as a marker
that indicates a multi-part Zip archive which has only one part.
libarchive in -CURRENT now recognizes and ignores this marker.
993 down, two to go. ;-)
