Something like that might be reasonable, but what sort of return
values do you think would be appropriate, exactly?  That is, can you
take a look at the latest diff source code, find every instance of
returning 2 from diff, cmp, sdiff, etc., and describe what value you
think should be returned instead?  It has to be an integer greater
than or equal to 2, preferably a small number.

I worry a bit that adding to much detail here will just confuse the
user, and that it might be simpler to just stick with 2.
