-S prints incorrect number of bound tasks

In rts/Stats.c we have:

            statsPrintf("  TASKS: %d (%d bound, %d peak workers (%d total), using -N%d)\n",
                        taskCount, taskCount - workerCount,
                        peakWorkerCount, workerCount,
                        n_capabilities);

but I think taskCount - workerCount must be wrong, because taskCount is the current number of tasks, while workerAcount is the total number of workers (accumulating). I think it should be:

            statsPrintf("  TASKS: %d (%d bound, %d peak workers (%d total), using -N%d)\n",
                        taskCount, taskCount - currentWorkerCount,
                        peakWorkerCount, workerCount,
                        n_capabilities);
