support.ownLast is "false" in all but IE < 9

support.ownLast is "false" in all but IE < 9. I guess a short way to describe that is "none but IE < 9" but having "all but IE < 9" is misleading. As the rest of the support properties (e.g. funcNames) return "true" when you have a browser that fits in the "all" part.

jdalton asked to just use "(IE < 9)" instead of "(none but IE < 9)".
