I've fixed this in the emacs-25 branch. Surprisingly, the remote case
shows also two `changed' events when backing up by copying. Maybe this
is a sign that Tramp's implementation could be optimized, dunno. When
time permits I'll debug.

kqueue does not keep file notification when backing up by rename. That's
expected, because it cannot watch whole directories for changes. Maybe
I'll drop a short not in the manual.

Best regards, Michael.
