Attachment: testcase that works correctly

This testcase doesn't have newlines in the string.  Such newlines are certainly
invalid CSS for the string data type -- I need to double-check that the same
applies to URLs (but even if they were -- what would the URL parser do with
them?).

Yes, it should be clear from the tokenization in
http://www.w3.org/TR/CSS21/syndata.html#tokenization (although it isn't clear
from the prose on URLs) that newlines must be escaped by backslash within strings.
