You lost me.

Do you mean to say that you always interpret the above hunk as:

   @@ -10,4 +10,4 @@
    context before
   -old 1
   +new 1
   -old 2
   +new 2
    context after

and call "replace 'old 1' with 'new 1'" as "change 1", "replace 'old
2' with 'new 2'" as "change 2"?

If it is what you are doing, it does not make much sense to me.  "new 1"
may correspond to "old 1" and "old 2" while "new 2" may be an independent
addition.  E.g.

   @@ -10,4 +10,4 @@
    context before
   -#define add(x,y) \
   - (x) + (y)
   +#define add(x,y) ((x)+(y))
   +#define sub(x,y) ((x)-(y))
    context after

I might want to pick bugfix of add() definition without using the new
definition of sub().

Please call

	"-old 1" - change #1
        "-old 2" - change #2
        "+new 1" - change #3
        "+new 2" - change #4

and try explaining what you are doing again, pretty please?
