Type of i defaults to i32 when usize should be used.
It's only a problem if this function is called with two iterators longer than i32::MAX. It seems unlikely to me but who knows?
i32 should not be the default integer type in the library. usize would have more sense so I add the lint as warning (for the library only, it's okay in tests and benchmarks).

See lint doc: https://rust-lang.github.io/rust-clippy/master/index.html#/default_numeric_fallback

Type of `i` defaults to `i32` when `usize` should be used.
