Add failing unit test for smarty

Added this failing test:

    "Ellipsis within quotes..."

The second double quotes should be rdquo, but smarty makes ldquo. I tried to figure out where the bug might be, but I couldn't narrow down the bug because all of these cases succeed:

    "One period."
    "Two periods.."
    "Semicolon;"

There must be something about the order of regexp evaluation I'm not understanding.
