English Jon- Whilst whippet's use of "i'nt" may have simply been an error as you suggest, when I first read it I presumed (s)he was using it to imitate the common spoken form, as in the "Int milk brilliant!" catchphrase from The Fast Show. If our American friends can use *ain't*, then we can have *int* if we want!Having said all that it probably was just a typo.
And I'm just waiting for someone to resurrect the debate about the anti-semitic nature of morris dancing again....
