commit 20a74b9d377c812abca651cb7ed7b4625ead76b1
Author: Ken Gaillot <kgaillot@redhat.com>
Date:   Thu Jan 12 12:48:40 2017 -0600

Fix: tools: properly ignore version with crm_diff --no-version
    
    Previously, crm_diff --no-version would remove the <version> information from
    the generated patch, but it would still generate a change to update the
    version. Now, it doesn't generate that change.
    
    Based on patch originally provided by Andrew Beekhof <andrew@beekhof.net>
