nit: I would have made this take an int extension_count, because i18n is
potentially a lot trickier than just differences in singular vs plural (even
though the problem you are trying to solve is just that).

Yeah, that's probably better.  Done.

         const base::string16& overflow_count) const = 0;
     virtual base::string16 GetLearnMoreLabel() const;
