Subject: Better support for command line scripts which want to set the default
 language to the value of $LANGUAGE (or any of the other gettext module
 supported environment variables).  Specifically,

set_language(): Allow the `language' parameter to default to None,
which tells gettext.translation() to use its own defaults.

When the module global _translation is None, call set_language() with
no arguments.
