I'm going to correct myself once more. It seems like this has changed between 
spec revisions, and per the [final 
spec](https://www.w3.org/TR/css-easing-2/#linear-easing-function-parsing), even 
though the syntax uses the "one or more" modifier, the parsing algorithm adds 
the following restriction:

So I'm going to change that again, and add an appropriate IAE if length < 2.
