+/* We introduce new member `tab_offset'. We need it because of the
+ existence of wide-column characters. There is a case that the
+ line-break occurs at a wide-column character and the number of
+ colums of the line gets less than width.
+
+ Example (where W_ stands for a wide-column character):
+ ----------
+ abcdefgh\\
+ W_
+ ----------
+
+ To handle this case, we should not calculate the tab offset by
+ tab_offset += width;
+
+ Instead, we must remember tab_offset of the line.
