Hm.  That must be the relevant difference.  I just repeated the experiment
on a Fedora 28 box with reasonably up-to-date bash:

$ /bin/sh --version
GNU bash, version 4.4.23(1)-release (x86_64-redhat-linux-gnu)

and it behaves the same as my RHEL6 box: no problem with the direct
invocation of unzip, problem if use a pipeline.

Anyway, we know what to do, so I'll go do it.
