Agreed.  There are tools that assign special meanings to separate >0
error codes, i.e. diff3(1) which exits with:

    0   when successful

    1   when there are conflicts in the three files being merged

    2   when something unexpected but bad nonetheless happens

Being precise about the error codes is critical in this case.  It may be
equally important in other places too.
