One of the places where zsh differs from other shells, doing the right 
thing.

One possibility is to set the shwordsplit option, if you really want
it everywhere. Our you can force word splitting for that one parameter 
expansion by using: `$=PRGARG'.

The best way would be to use an array, though.

  PRGARG=(-bla1 -bla2 -bla3)
  $0 $PRGARG
