FYI: code_start is not initialized for epilogue

        * src/scan-gram.l (code_start): Always initialize it when entering
        into yylex, as SC_EPILOGUE is activated *before* the corresponding
        yylex invocation.  An alternative would be making it static, but
        then it starts with the second %%'s beginning, instead of its end.
