The weirdness is --amend let you replace one file with another with same data and flags if the new file copy record differ from the one in the parent revision. In theory, there is no problem with this kind of thing, subversion supports it, but here we see log and status disagree. The reason is log reads the copy record from the filelog, while status calls copies.pathcopies() which eventually invokes some expensiveness argument to discard this case (copies.py, _forwardcopies(), line 132). Since the next patch will side with pathcopies(), I prefer to call this behaviour a bug.
