`-ms-flex-pack: distribute` causes warning

[drukepple]

justify-content: space-around; has been auto-prefixed to, among other things, -ms-flex-pack: distribute for IE 10 support, and the linter claims that distribute is not allowed, that start | end | center | justify is the allowable list. This is not true, although I've found contradictory documentation on the matter. This page indicates that distribute is valid:

And this Code Pen, when viewed in IE, indicates likewise:

I created a PR in parser-lib to add the 'distribute' property :)
CSSLint/parser-lib#241

My changes got merged, I stopped getting the 'distribute not allowed' error. Someone might be able to assist if you post the relevant parts of your code and the error you're getting.
