IMHO, it's not a bug: `diff' (which is the comparison engine used by
`sdiff', try "diff -c old new" in your case and you will see the same
``problem'') is not guaranteed to generate a result that is
``correct'' in your sense of the word.  It is just guaranteed to
produce a result that represents the differences accurately, that's
all.
