Bug#699755: yui-compressor: Broken css with @charset

[Roman V. Nikolaev]

Package: yui-compressor
Version: 2.4.2-2
Severity: normal

I use At-rule @charset for CSS (http://www.w3.org/TR/CSS21/syndata.html#at-
rules). Then I apply compressor for my css file browser get it as broken and
don`t apply any styles.

I think for at-rules yui-compressor must save "\n".

Reproduce:
1. CSS file main.css looks like this:

@charset "UTF-8";
h1 { color: blue }

2.  yui-compressor --type css main.css, you get:

@charset "UTF-8";h1{color:blue;}

3. Iceweasel 18.0 don`t apply any styles from main.css
