I think this never got included because it didn't play nice with the  
new dollar arg expansion code.  So this patch at this point serves as  
a starting point for developing this.

As for what "bla-$@-blu" means, it doesn't matter as long as $$, $@,  
and $# are clearly defined.  By bash rules, that would give you "bla- 
my list of words-blu".
