I see, I hadn't thought about mixed-revision working copies.
Thanks for the reply.

(I was thinking about diffs on single files, i.e. "svn diff -r
<what happens to be BASE> file". The reason I asked was because
vc-svn.el does "svn diff -r <what happens to be BASE> file"
instead of "svn diff file" -- quite unusable when off-line. I did
consider this to be more easily fixed by vc-svn.el so I did submit
a patch to Emacs before asking Subversion. I thought it could be
a nice harmless improvement to all clients, but I suppose it's not
worth worrying about.)
