Coverity complains that the return value from gettuple_eval_partition (stored in variable "datum") in a do..while loop in WinGetFuncArgInPartition is overwritten when exiting the while loop. This commit tries to fix the issue by changing the gettuple_eval_partition call to: (void) gettuple_eval_partition() explicitly stating that we discard the return value. We are just interested in whether we are inside or outside of partition, NULL or NOT NULL here. Also enhance some comments for easier code reading.
