checkcopies: add logic to handle remotebase

As the two _checkcopies passes' ranges are separated by tca, not base,
only one of the two passes will actually encounter the base.
Pass "remotebase" to the other pass to let it know not to expect passing
over the base. This is required for handling a few unusual rename cases.
