Rollup merge of #44712 - oconnor663:copy_test, r=GuillaumeGomez
fix an incorrect assertion in the doc example for `std::io::copy` I think this wasn't caught by CI because the `foo` wrapper function was only defined and not called. This seems to be the norm for doc examples that define a `foo` function. Is that on purpose?
