  This patch completes the fixes nec. to make 1.4 asterisk dialplan expressions ($[...]) 8-bit transparent

  While I was updating ast_expr2.fl, I missed one rule that would allow 8-bit chars to be caught
  in tokens; and in so doing, it absorbs the ${ sequence and messes up the
  checking of raw exprs by AEL.

  Trunk already has these changes.
