Look at the @@ line. One tells you in which function the line is added,
the other one doesn't. It always pisses me off when reviewing patches
cause then I have to figure out the function based on the label,
surroundng context, and/or line numbers.

I'm also thinking this may have caused some of the numerous misapplied
patches we've had since our labels all tend to be similar.
