From f8ec916731ef8d81eefc5db61e3405dade65d821 Mon Sep 17 00:00:00 2001 From: Daniel Barkalow Date: Wed, 18 Nov 2009 02:42:30 +0100 Subject: Allow helpers to report in "list" command that the ref is unchanged Helpers may use a line like "? name unchanged" to specify that there is nothing new at that name, without any git-specific code to determine the correct response.
