man page: minor problem regarding ${parameter@operator}

[Clark Wang]

See:

       ${parameter@operator}
              Parameter transformation.  The expansion is either a
transforma-
              tion of the value of parameter or  information  about
parameter
              itself,  depending on the value of operator.  Each operator
is a
              single letter:
              [...]
              If parameter is @ or *, the operation is applied to  each
posi-
              tional  parameter  in  turn,  and the expansion is the
resultant
              list.  If parameter is an array variable subscripted with  @
or
              *,  the case modification operation is applied to each member
of
              the array in turn, and the expansion is the resultant list.

In the last sentence, "the case modification operation" should be "the
operation".
