We notice they sure blew it with the character width. From looking at
the indentation, they assume that double width (Chinese) characters
are single width!

Also if one turns on show-trailing-whitespace, whitespace of shame is
revealed.  However, as this buffer isn't usually saved to a file, I
can still go on with my life in this case.
