I would not be averse to seeing diff show actual differences between
current and last-changed revision in the -cN or -rN-1:N case, with or
without --git. Both parameters mean, "what changed in revision N".
The point where this breaks is when you want to create a diff that can
be applied by plain-vanilla patch and will remove one file and add
another one. That case requires different output, and maybe
--show-copies-as-adds is the right option to use in that case (but I'd
prefer to call it "--patch" or something more semantically close to the
Note that IIRC patch will parse the index header, so that you can have:
