I do not like that approach at all: it will miss small differences
introduced inadvertently by changes, making the test less useful, but
would detect falsely rounding differences that fall near the cutoff
(0.499 -> 0.501).

I had posted I script to make approximate comparisons of text files; I
still like this approach better.
