+        * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
+        All uses changed.
+        (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
+        Rename locals to avoid shadowing.
+
         * casefiddle.c (casify_object, casify_region): Now static.
         (casify_region): Mark local as initialized.
