Subject: [PATCH 1/3] Allow builtin-fetch to work on a detached HEAD
Message-ID: <20070916063126.GA6487@spearce.org>
URL: https://gitlist.dev/e/20070916063126.GA6487%40spearce.org

```
If we are running fetch in a repository that has a detached HEAD
then there is no current_branch available.  In such a case any ref
that the fetch might update by definition cannot also be the current
branch so we should always bypass the "don't update HEAD" test.
