Subject: [PATCH v3 9/9] doc: trailer: add more examples in DESCRIPTION

From: "Linus Arver via GitGitGadget" <[email-masked]>
Date: Tue, 06 Jun 2023 02:08:24 +0000

From: Linus Arver <[email-masked]>

Be more up-front about what trailers are in practice with examples, to
give the reader a visual cue while they go on to read the rest of the
description.

Also add an example for multiline values.
