Smart quotes mechanism is based on regexps. There are unavoidable
ambiguous cases, like this one. We can pile up new rules to handle most
of them, but in the end, I don't think we cannot handle them all. Worse,
some advanced rules may create false positives.

Anyway, here are some options :

  1. Do nothing.

  2. Change the closing regexp to
     "\\(?:\\w\\|\\s.\\|\\s_\\)\\([\"']\\)", i.e. ignore characters
     after the quote. But then we have to find a way to know a closing
     single quote from an apostrophe.

  3. Do not rely on regexps but on some simple depth rules:

     1. At a given level in the parse tree, the first quote is always an
        opening quote ;

     2. Every subsequent quote in the level alternates between closing
        and opening state.

Second option probably has its shortcomings too, but it may be sturdier.
It also doesn't solve the problem of apostrophes.
