This introduces a new command-line option: --exit-code. The diff 
programs will return 1 for differences, return 0 for equality, and 
something else for errors.

I am not convinced that this exit code (even if expected by experience) 
makes sense. A diff should _only_ fail if anything goes _wrong_, not if 
the files are _different. That is what cmp is for, no?

Not really, if you are used to use diff as a replacement for
cmp.
