OK, you've both convinced me now. I agree that diff -c could trace
copyfrom even if the copfrom rev is outside the operative revision
range, and display an 'added' file only with --show-copies-as-adds.

Now, the problem is that the repos->repos diff case doesn't support
--show-copies-as-adds yet (see do_diff() in libsvn_client/diff.c).
So it's not a trivial fix and might require some work to get done.
