I've had a slightly closer look at gzip... making gzip -l able to recognize multiple chunks archive should be doable, but it would require a lot of code churn. More precisely, the gz_read code has a check that we arrived at the end, it tries to read a new header, and it keeps going if it can. So this would require seeking on the input file, trying to read a new header and displaying it. I'm pretty sure it's not worth it. if you need looking at chunked tarballs further, there's some code in regress/usr.sbin/pkg_add/extract_chunks that does precisely that: look at the actual boundaries, and uncompress each chunk separately.
