Re: [PATCH v2 6/6] fetch: add 'refs/bundle/' to log.excludeDecoration

> 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

> 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).
