Subject: [PATCH v6 3/8] branch: lowercase error messages

From: Anders Kaseorg <[email-masked]>
Date: Fri, 12 Nov 2021 19:33:53 -0800

Documentation/CodingGuidelines says “do not end error messages with a
full stop” and “do not capitalize the first word”.  Reviewers requested
updating the existing messages to comply with these guidelines prior to
the following patches.
