193 *
194 * <p>By default, copy detection is <em>on</em>, as it's reasonably cheap. However,
195 * in certain scenarios it may be reasonable to turn it off, for example when it's a merge
196 * of two very different branches and there are a lot of files added/moved.

199 * implement {@link HgStatusInspector#copied(Path, Path)} ;)
