Bugfix: be sure to delimit trailing \ if it is an the end of a quoted content

What happens is that if the content is (ignore single quotes): 'hell o\'.
The fss extended content conversion should be (include double quotes): "hell o\\".
The code must realize that the last \ is a would end up before a quote, or one would get: "hell o\".
That content string would then be classified as an unterminated group.
