Mmm. You're using vi. Probably opens the file in textmode. Is anything
perhaps translating every LF to CR+LF, thereby adding an 0x0d in front of
every 0x0a in the original file? The way to find out would be
tr -c -d '\012' < blafile | wc -c
and if the result is 197954, there's your suspect.
cheers,
