With fix to add unfenceinst


[root@ask-02 ~]# ccs -f test --createcluster cluster
[root@ask-02 ~]# ccs -f test --addnode testnode
Node testnode added.
[root@ask-02 ~]# ccs -f test --addunfenceinst blah testnode

If you look at the file 'test' it includes an unfence section

[root@ask-02 ~]# ccs -f test --rmunfenceinst blah testnode

The file 'test' still has an unfence section, but it is empty.

fix verified in ccs-0.16.2-35.el6
