#13163: fix names of _get_socket args

This was already done in Python3, but having it wrong leads to
incorrect debug output, so it seems worth fixing in 2.7 as well.

Patch by Victor Terrón.

       Transfer Encoding now happens implicitly based on the *_charset*
       argument.
 
+   Unless the ``_charset`` parameter is explicitly set to ``None``, the
+   MIMEText object created will have both a :mailheader:`Content-Type` header
+   with a ``charset`` parameter, and a :mailheader:`Content-Transfer-Endcoding`
+   header.  This means that a subsequent ``set_payload`` call will not result
+   in an encoded payload, even if a charset is passed in the ``set_payload``
+   command.  You can "reset" this behavior by deleting the
+   ``Content-Transfer-Encoding`` header, after which a ``set_payload`` call
+   will automatically encode the new payload (and add a new
+   :mailheader:`Content-Transfer-Encoding` header).
