Problem:  With 'nowrap', when a line ends with a double-width character
          exactly at the window width and has wrapping "after" virtual
          text, the lines below disappear and "@@@" is shown.
Solution: Detect that the last character fills the rightmost column using
          its cell width, so a double-width character is handled the same
          as a single-width one.  Also clarify in the help that "wrap"
          only takes effect with the 'wrap' option set.
