I think we may as well lint it. It has actually already diverged a little from being a direct cut and paste through various small edits  - and I don't imagine we would be particularly interested in upgrading it since presumably it is "working already"... with the possible exception of $.isPlainObject which looks suspicious to me. The fact that it is harmlessly already stuck at a 1.6.1 level is suggestive of how aggressive we might be likely to be about keeping it updated : P
