  This would probably be simpler to arrange using defadvice to define some before advice on shell-command. It's similiar to this Perl:

  sub foo {
    print "foo";
  }
  # Later on...
  {
    my $orig = \&foo;
    *foo = sub {
      print "before foo";
      $orig->(@_);
    };
  }

    This is snazzy! I suspected elisp must have some sort of around-ing like this, but I had no idea where or how to access it. Thanks!

      I picked it up from Writing GNU Emacs Extensions [oreilly.com]. I don't think it's in print any more, but if you can find a copy, it's a good read.
