Erik said '"diff" the _code_'. I agree with him.
the diff should not only ignore white spaces and CR, but it could also
compare tokens. For example, renaming a local variable does not
produce a really different function. Permuting two functions
is a nightmare with SCCS although the semantics of the code is not
changed.
