You did something very wrong then. This should have produced files that
were larger not smaller than the originals (not a lot larger, unless
there were huge numbers of carriage returns, but definitely not smaller).
It's worth asking whether there really were carriage returns in your
data in the first place. Maybe they were artifacts of having
transferred the dump file through a Windows machine?
