I understand that - my point is the behavior is different for normal
adds vs add-with-history.

I know the results are the same in 1.4.x (and presumably earlier), but
the thing that frustrates me about this is that the diff gives
absolutely no indication there is anything changed given a file added
with history, which seems wrong to me. My personal interpretation of
the diff command was always "what is different as compared to the last-
updated-rev of the wc?" which isn't what it actually does - I'm
raising a UI question, not actually saying it's wrong. Does anyone
else see the expected behavior I do, or am I the odd case out? It
doesn't feel "right" to be doing the diff of a copied file against the
copy source, but instead against the path.

Thanks,
