That's the Deveraux(?) addendum in action. shuffle+replace = 3 in the
distance score, while remove = 4 (I think).

Typos by users accustomed to computers are more often of the shuffle
(haed vs head) or replace (hwad vs head) kind, while those less
accustomed often fumble more and press more keys. For this case though,
I agree it gives a rather strange result.
