Small files fail silently

The program fails silently on small files. See Debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549292 for an example. This problem should be noted somehow by the program or at least documented.
In the referenced example, there is no need to print a message about not producing output. The files are too small to be compared. We can't print a message for every one of these, or the output will just be a series of warnings.
Instead adding a warning when the program doesn't process any file large enough to produce a meaningful result.
