Yes, and it works, thanks. I simply thought there was an embedded
function to invoke the shell command with arguments.
However, I've used this:

          (perl (format "perl - %s"
                argv)))
      (shell-command-on-region b e perl)))

without the quoting around argv because otherwise multiple arguments
(all into argv) would have been seen as a single one on the Perl side.

Thanks.
