Fix swiftclient help

Command help was wrong in some cases. While we're at it, add some
defaults to help and change some brackets to be consistent with
http://en.wikipedia.org/wiki/Command-line_interface#Command_description_syntax

Remove tox locale overrides

* tox.ini: The LANG, LANGUAGE and LC_ALL environment overrides were
introduced originally during the testr migration in an attempt to be
conservative about the possibility that locale settings in the
calling environment could cause consistency problems for test runs.
In actuality, this should be unnecessary and any place where it does
cause issues ought to be considered an actual bug. Also, having
these in the configuration actively causes older pip to have
problems with non-ASCII content in some package metadata files under
Python 3, so drop it now.
