[PATCH 1/3] Allow builtin-fetch to work on a detached HEAD

Shawn O. Pearce· Sep 16, 2007, 06:31 UTC · lore

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.
