string-no-newline

Disallow (unescaped) newlines in strings.

a {
  content: "first
    second";     ↑
}                ↑
/**              ↑
 * The newline here */

The spec says this: "A string cannot directly contain a newline. To include a newline in a string, use an escape representing the line feed character in ISO-10646 (U+000A), such as "\A" or "\00000a"." And also: "It is possible to break strings over several lines, for aesthetic or other reasons, but in such a case the newline itself has to be escaped with a backslash ()."
