I've come across this too.  Personally I'm not sure what use "-C" is.  From 
the manpage, man git-diff-files (no, this isn't the place I'd look either).

--find-copies-harder
For performance reasons, by default, -C option finds copies only if the 
original file of the copy was modified in the same changeset. This flag makes 
the command inspect unmodified files as candidates for the source of copy. 
This is a very expensive operation for large projects, so use it with 
caution.

That is to say that unless the file you are copying was modified AND copied in 
the same commit, it won't be searched as a potential source for the copy 
operation.  I think it would be rare to make a copy of a file I had modified, 
surely I'd want to check in modifications before making a copy?

Regardlss, to get the results you want, use the stronger 
switch --find-copies-harder, heeding the warning that on big projects it will 
be very slow.
