It is a bit sad (not your fault) that this is not shown as a
rename+modification patch, as most of the logic seem to be straight
out of the original.

This is inherited from the original, but the hardcoded "3" feels a
bit brittle.

Would ARRAY_SIZE(expected_contents)-1 always match the expected
number, I wonder?  Even if it is, improving it is totally outside
the scope of this topic.  I am just mentioning this since I will
forget if I don't ;-).
