Implicating wrong_feet -> error.

Reason: Seems like this would make sense unless there's a specific reason not to.

I didn't even know wrong_feet existed until now; it'll be handy.

Someone could draw "wrong feet" on purpose; while I guess an intentional error could still be an error, a subject might correctly have "wrong feet". Not that I can think of any examples.

The wiki for wrong_feet clearly states that it has to be an unintentional mistake though.
But really, wrong feet on purpose seems way too unlikely, and would require reading the author's mind anyway. In my opinion, they should be aliased.

Minoriko would be the only one who might that description. Other than that, I agree with the alias as well.
