Ah, it sounds like you're worried about misuses like (format filename), where 
FILENAME might contain arbitrary characters including curved quotes.  However, 
code like that has always been buggy, as FILENAME may include %% (or % followed 
by something else, of course) and the %-sequences would be misinterpreted too.

Bugs like that do exist on occasion, but the recent change to ‘format’ hasn't 
introduced significantly more opportunities for them.
