Consider white-space : pre-line as a native part of hint--large

Thanks for your beautifully structured and commented scss.

On those rare occasions when I put more text in a hint than most people would consider doing, I want to be able to use newlines within the hint. Unsurprisingly, this always coincides with using hint--large. As such, after I load hint.css, I drop this in:
.hint--large:after {
white-space : pre-line;
}
In other hint--sizes, pre-line doesn't play well, but as best I can tell, in hint--large it has no impact on normal amounts of text (it's backward-compatible), and is helpful for the rare, long hint that benefits from being broken up by newlines. As a practical example, consider a frequently useful hint for password fields such as:
At least one each of upper case, lower case, numeral, and other character.
At least 12 characters long.
It's not very long, but it's a bit bulky without the injected newline, and I think easier to read with the newline.
