There is a much better algorithm for comparing files that is not
only linear time/space, but also outputs differences in a way
superior to DIFF. See "A Technique for Isolating Differences Between
Files" by Paul Heckel, CACM April 1978. A good C programmer can
implement the algorithm in a day. There are very successful versions
running on TOPS-20 and the Apollo.
