Hi,
I suspect this patch is wrong and the code is meant to print in either
case.
Neil?

Looking at the whole
if (failed_slot1 == -2 || failed_slot2 == -2) {
statement it looks like every path through should print a message, and
this section would be more similar to the previous section if, as you
say, the code prints in either case.
So I agree: original code is correct, indentation is wrong.
