From: Nguyễn Thái Ngọc Duy Date: Wed, 03 Feb 2016 09:35:41 GMT Subject: [PATCH 11/20] worktree.c: recognize no main worktree Message-ID: <1454492150-10628-12-git-send-email-pclouds@gmail.com> In-Reply-To: <1454492150-10628-1-git-send-email-pclouds@gmail.com> Because HEAD is part of repository signature, even if it's per-worktree file, we can't simply delete it. So main worktree is considered gone if .git/HEAD contains all-zero SHA-1.
