Well, not always, maybe? There are "real" revision differences and
"fake" ones. For example, suppose I do this:

   $ svn co http://blahblahblah.com/repos/myproj/trunk/ myproj
   [...]
   Checked out revision 1729.
   $ cd myproj
   $ svn up -r 1728 foo.c
   $

Let us assume that foo.c did not change in r1729 -- in fact, say foo.c
hasn't changed since r1. If I now do

   $ svn cp -m "Make branch." \
       http://blahblahblah.com/repos/myproj/trunk/ \
       http://blahblahblah.com/repos/myproj/branches/newbranch/
   Committed revision 1730.
   $

...would we expect to see exactly one path in the 'svn log -v' output
for r1730, or two -- one add-with-history to create the branch from
r1729 of trunk, and another to splice foo.c@r1728 into that branch?

I'm not doing a very good job of articulating what I mean by a truly
mixed-revision working copy versus a fake one, but I think you see
what I mean. In a fake one, those cases where an object's revision
differs from that of its parent are spurious: were you to update the
object to its parent's revision, the node revision identity of the
object wouldn't actually change.
