Re: Diff output inconsistentices

I also feel this inconsistency annoying. Can we also have the option
"--no-diff-added" or "--diff-copy-from" for svn diff? I've noticed
that explicitly specifying --old and --new might give similar effect,
but this doesn't help much if one revision contains several file copy
operations with different sources/destinations (e.g., when you move
things around).
