I am manually using the number guessing method:
- If there are 12000 lines, I go to middle of that one, like line
6000, somewhere from there up or to bottom, I do M-x eval-region
- Then if there is failure, I go to half between x and 6000, if it is
in bottom region I go to line 9000 and eval region from 9000 to
12000;
- Then if problem is between 6000 - 9000, then I go to to half of it,
to line 7500 and again verify 50% of region;
That way I arrive fastest to the location.
Could that same algorithm be used in Emacs for function to narrow it
to lines from X to Y?
