The latest code I posted 2003-08-19 has an implementation of exactly
same idea. It first doubles search ranges, and if differences are
still not found, then it starts to halve a matching substring size.
So there are no problems with finding differences anymore. It works
correctly in all cases I tested.
However, I think that the size of matching substring should be
customizable. I found that current default value 32 (with which a
search is started) is optimal for most cases. But sometimes user
may want to start with a lesser value to get more fine-grained results.
