BTW,
I tend to consider narrow-to-region in Elisp as a problem,so I encourage
you to write your code without it.
In your example, you don't need to narrow: the only thing you need is
to keep the "end" updated when the buffer is modified, which is easy to
do by changing the "end" form an integer to a marker.
Or alternatively, you can simply work your way backward, in which case
you don't need to worry about using a marker since the "start" position
to which you're going won't be affected by the buffer modifications.
Stefan
