Does that look correct to you? It seems to me (but I could very well be wrong) that if we use the actual narrowing bounds inside decode_mode_spec, the mode line will contain the correct information. Another way to do it would be to unset and reset the locked narrowing for each buffer in the loop inside redisplay_mode_lines, I think.
