+/* 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.
