Log message:
        * src/parse-gram.y (CHARACTER): Remove unused token.
        All uses removed.
        
        * src/scan-gram.l: Remove stack option.  We no longer use the
        stack, since the stack was never deeper than 1; instead, use the
        new auto var c_context to record the stacked value.
        
        Remove nounput option.  At an unexpected end of file, we now unput
        the minimal input necessary to end cleanly; this simplifies the
        code.
        
        Avoid unbounded token sizes where this is easy.
        
        (unexpected_end_of_file): New function.
        Use it to systematize the error message on unexpected EOF.
        (last-string): Now auto, not static.
        (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
        (scanner_last_string_free): Remove; not used.
        (percent_percent_count): Move decl to just before use.
        (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
        not the (never otherwised-used) CHARACTER.
