-/* 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.
