D6727: fix: pass line ranges as value instead of callback

REVISION SUMMARY
  The callback no longer takes any arguments from the inner function, so we might
  as well call it sooner and pass the value instead. Note the value still needs
  to be recomputed every iteration to account for the previous iteration's
  changes to the file content.
