    allout.el: fix subtree expose numbering bug
    
    * lisp/allout.el (allout-process-exposed): Reverse the list of indices
    properly so that the correct numbering for nodes in a subtree is used.
    Avoid destructive reversing; the list may be a constant (literal).
    This flaw was revealed by an ignored-return-value warning.
