If needed, I think we could make it work reasonably cheaply with something along the lines of (100% guaranteed untested code): (let (pos lines (eol-offset 0)) (while (progn (setq pos (byte-to-position (+ pm byte (- eol-offset)))) (setq lines (1- (line-number-at-pos pos))) (not (= lines eol-offset))) (setq eol-offset (+ eol-offset lines))) pos)) -- Stefan
