I just created a repo with a single file "foo" and then renamed it to
bar.  The result of the command you proposed is as follows:
        
        [12:25:02 yminsky at nyc-qws-015 foo]$ hg status -arC --rev 0:1
        A bar
        R foo

That looks like bar was added and foo was removed.  I'm not sure how I
can detect that bar is actually a copy of foo from this.
