Thanks, I went for that.

Please find attached the next version of the patch.  I added tests not
only for zip and split zip detection, but also for all archivers that
follow the calling pattern

  ARCHIVER PARAMETER... ARCHIVE FILE...

and that I could easily install on my GNU/Linux system.  Which were
surprisingly many.

Of course, such tests are highly OS-dependent any have the potential
of causing a lot of failures, even though I tried to code them in a
defensive manner.

WDYT?

Thanks.
