I am not worried about the case in which patch author actively
"tries to" deceive.  It is more like "I am more likely to fail to
spot mistakes the patch author failed to spot himself", when I start
with reasoning, service provider implementations and then service
consumer.  When I am forced to think the problem myself before
seeing the answer and then compare the result with patch author's
answer, I am more likely to find such a mistake.

I took a brief look at diffcore-order.c; I do not think "/*.c" would
match only top-level .c files like gitignore files would.
