Allow whitespace within var function

[colinmeinke]

Input:

:root { --foo: red; }
.bar { color: var( --foo ); }

Expected output:

.bar { color: red; }

Actual output:

.bar { color: var( --foo ); }

Thanks for the report, just tested in Firefox which allows this. I can't exactly find it in the spec but I am sure it is laid out somewhere down the rabbit hole: https://drafts.csswg.org/css-variables/#syntax
