[PATCH 06/24] fetch: add 'refs/bundle/' to log.excludeDecoration

Message-ID: <701a983eed2e695e91b7a9abc50c64b25415d8a6.1653072042.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.1234.git.1653072042.gitgitgadget@gmail.com>

From: Derrick Stolee <derrickstolee@github.com>

When fetching from a bundle URI, the branches of that bundle are stored in a different ref namespace: refs/bundles/. This namespace is intended to assist with later 'git fetch' negotiations with a Git server, allowing the client to advertise which data it already has from a bundle URI.

These references can be confusing for a user when they appear as a decoration in 'git log' output. Add "refs/bundles/" to the multi-valued log.excludeDecoration config value. This is similar to the way "refs/prefetch/" is hidden by background prefetch operations in 'git maintenance' as added by 96eaffebb (maintenance: set log.excludeDecoration durin prefetch, 2021-01-19).
