From fe55851624bbdb4f08e17e27ef8197ed610ac586 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Thu, 1 Feb 2007 12:33:23 -0500 Subject: [PATCH] prevent HEAD reflog to be interpreted as current branch reflog The work in progress to enable separate reflog for HEAD will make it independent from reflog of any branch HEAD might be pointing to. In the mean time disallow HEAD@{...} until that work is completed. Otherwise people might get used to the current behavior which makes HEAD@{...} an alias for @{...} which won't be the case later.
