Subject: [PATCH v5 12/27] refs: forbid cross-backend ref renames
Date: Thu, 18 Feb 2016 00:17:35 -0500	[thread overview]
Message-ID: <1455772670-21142-13-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1455772670-21142-1-git-send-email-dturner@twopensource.com>

This would be pretty weird, but since it will break, we should prevent
it.
