 Even if one argued that "Testing ${@} fnord" is a meaningful
 substitution, then according to the above definition, it should produce
 zero arguments if there are no positional parameters. Yet,
     sh -c 'foo() { echo "Testing ${@} fnord"; }; foo'
 produces (on 3.0)
     Testing  fnord
 which I must consider a bug.
