[issue13457] Display module name as string in `ImportError`

[Ram Rachum]

New submission from Ram Rachum <ram at rachum.com>:

Recently I was confronted with a mysterious error:

    ImportError: No module named datetime

Firther investigation revealed that the cause was a pickling problem that ran `__import__('datetime\r')`.

If `ImportError` would have shown the module name as a string, there would be no ambiguity:

    ImportError: No module named 'datetime\r'
