Starting at line 262:
Note that some of the moves you could attempt to make with this method
are invalid - for example, trying to make an instance be its own its own
child or the child of one of its descendants. In these cases, a
``mptt.exceptions.InvalidMove`` exception will be raised.

At line 263 "its own" is repeated two times.
