[PATCH 3/4] git-p4: add raw option to read_pipelines

From: Joel Holdsworth <jholdsworth@nvidia.com>
Date: Dec 13, 2021, 22:54 UTC
Message-ID: <20211213225441.1865782-4-jholdsworth@nvidia.com>
In-Reply-To: <20211213225441.1865782-1-jholdsworth@nvidia.com>

Previously the read_lines function always decoded the result lines. In order to improve support for non-decoded binary processing of data in git-p4.py, this patch adds a raw option to the function that allows decoding to be disabled.
