[PATCH 17/20] git-p4: compare to singletons with "is" and "is not"

From
Joel Holdsworth <jholdsworth@nvidia.com>

Message-ID
<20220112134635.177877-18-jholdsworth@nvidia.com>
In-Reply-To
<20220112134635.177877-1-jholdsworth@nvidia.com>

PEP8 recommends that comparisons with singletons such as None should be done with "is" and "is not", and never equality operators.

This guideline is described here: https://www.python.org/dev/peps/pep-0008/#programming-recommendations
