Don't want similar symbols to match pattern

Hi,

I have two symbols, x and x with a subscript. 

Is there any way I can define the function f[x_] (a function of x and
subscripted x) but not pattern match on the subscripted x? Example
below.

(Renaming my variables would probably be a painful experience, as I
intend to use the output in a document requiring the subscripted
versions.)

thanks

Joe

e.g.

Cell[BoxData[
    RowBox[{
      RowBox[{"f", "[", "x_", "]"}], "=", 
      RowBox[{"x", "-", 
        SubscriptBox["x", "1"]}]}]], "Input"]
