[PATCH]: iostat: prevent endless loop

[Marek Polacek]

  Here's patch which prevents endless loop in main(), when there are no 
additional parameters specified. Now we have:

         if (count > 0) {
             if (--count == 0)
                 break;
         }

but when count is 0, we never get to that break, so we end up looping...
