| Removed the ``formatter`` module, which was deprecated in Python 3.4. | |
| It is somewhat obsolete, little used, and not tested. It was originally | |
| scheduled to be removed in Python 3.6, but such removals were delayed until | |
| after Python 2.7 EOL. Existing users should copy whatever classes they use | |
| into their code. Patch by Dong-hee Na and and Terry J. Reedy. |
