ed: handle Unicode beyond the BMP correctly in list mode.
List mode was constrained to the BMP. This change introduces
the following new list mode convention, using Go string literal syntax:
Non-printing ASCII characters display as \xhh.
Non-ASCII characters in the BMP display as \uhhhh.
Characters beyond the BMP display as \Uhhhhhhhh.
