Hi Kuroda-san,

I found one minor thing in the patch.

+                    appendStringInfoSpaces(buf,
+                                           padding > 0 ? padding : -padding);

Is it better to use Abs(padding) here ?
Although some existing codes are using " padding > 0 ? padding : -padding ".

Best regards,
