Actually inet(4) itself is a bug and deserves a PR. sin_len was added many,
many years ago.
In fact one could argue that the `right' thing to do would be to remove the
sin_zero field altogether. The reason the semantics for sin_zero are neither
documented nor obvious is that it has none; its presence is a historical
artifact, with the reason for its existence long gone.
I wonder what it would break to just remove it?
