[Python-Dev] [Python-checkins] cpython: fix doc typo for library/test.rst

[Eli Bendersky]

Actually I think this is no longer true.  import_fresh_module raises an
ImportError if *name* can't be imported, or returns None if the fresh module
is not found.

> (e.g. json) even when the acceleration (fresh=['_json']) was missing, and
> the C tests were run twice using the same pure-python module used for the Py
> ones.

> The typo and the wrong doc is also on 2.7.

Ezio, thanks. I opened issue 12645 to track this.
