Yes, I knew that.

I don't think an add (with or without history) can be done over an existing
file without the file being reported as deleted either at the same time or
previously. I may be wrong; that's just a feeling.

No hoops; the file was in fact deleted in between those revisions.

OK, I understand your explanation of why it behaves the way it does. Thanks.

I don't like it though. If I'd asked for the log in reverse chronological
order, its following of history in reverse order would have made more sense.
If the copy had been from one path to a different path, the reason for the
omission would have been more obvious. As it is, I feel I asked for the log of
changes to a certain item and it didn't show me all of them. Oh well, this
isn't as important as a definite bug so I'll leave it at that.

I'll accept that it's not a bug. The reason it behaves like that is not just
because it's doing history-based reporting, but because it's doing it backwards
(yes I know that's the canonical way to do it) even in a forwards log command.
  Oh well, that's just how it is. Thanks again for the analysis.
