Re: [csswg-drafts] [css-fonts-4] font-stretch valid values.

Doesn't matter whether it makes sense or not; percentages are floats, and so disallowing 0% would make the valid syntax an open range, which is disallowed as a general spec-design rule.  (For example, it makes it unclear what value `font-stretch: calc(-10%)` should clamp to.) 

Given that this is just a factor in the font-selection, not something used directly, there's nothing wrong with 0%; it just means you'll select the narrowest available font.
