Allow wide characters (properly encoded as byte strings according to LC_CTYPE) to be (perhaps part of) the "invisible" characters in a prompt, or the required prompt character which follows the literal sequence (this character must be one with a printing column width >= 1). The literal indicator character (which is just a marker, and not printed anywhere) (the PSlit parameter in sh(1)) can also be a wide char (passed to libedit as a wchar_t, encoded as that by sh(1) or other applications that support this.) Note: this has currently only been tested with everything ascii (C locale).
