which will work, independently of the A-B narrowing set by the user, and will reset the narrowing to A-B upon return.It will only work if [C..D] is inside [A..B]. It will not work if a Lisp program wants to widen [A..B], i.e. if [C..D] is larger than [A..B].
Hmmm... no, it will work for any values of [C..D]: (widen) is equivalent to (narrow-to-region 1 (1+ (buffer-size))), and in general the bounds given to 'narrow-to-region' are not limited by the current narrowing.
