2180 * and thus know what portions of the string to escape.
2182 * For instance, for:
2184 * g_markup_printf_escaped ("%s ate %d apples", "Susan & Fred", 5);
2186 * We form the two format strings "%sX%dX" and %sY%sY". The results

2189 * "%sX%dX" => "Susan & FredX5X"
2190 * "%sY%dY" => "Susan & FredY5Y"

2193 * where the two arguments differ, which tells us that the first
2194 * argument formatted to "Susan & Fred". We then escape that
2195 * to "Susan & Fred" and join up with the intermediate portions
2196 * of the format string and the second argument to get
