 Except that something is wrong here.  If I write a character which
 extends up to (but not beyond) the rightmost column of the terminal
 with addch or add_wch, then it sets __ISPASTEOL and leaves the cursor
 position at the *beginning* of the character.  It's only if I use addstr
 that the cursor gets into the one-past-the-end state.
