Yeah, I think we should refuse to export from a upstream- tagged
revision if it doesn't have any of the pristine tar delta *and*
bzrlib.export doesn't support the per_file_timestamps argument. That
should be sufficient to prevent accidentally bzr-builddeb from creating
a tarball with different timestamps.
