FLEX_PREFIX (FLEX_PREFIX (last_string)) in flex-scanner.h?

[Paul Eggert]

I installed this.  I don't know why the old code was working (perhaps
because C refuses to execute recursive macros? but this one isn't
recursive!) but anyway this is a minor simplification.

        * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
        since last_string is already defined to FLEX_PREFIX (last_string).
