This method was named reinitialize_command in distutils and accompanied by a comment suggesting to change it to get_reinitialized_command. Following that, I did the change for distutils2, but it proved confusing: The Distribution object has an internal cache of command objects, to make sure only one instance is ever used, and the name get_reinitialized_command could suggest that the object returned was independent of that cache, which it was not. I’m reverting the name change to make code clearer.
