commit 57e73ef3943638a6a3e937f86789f391e5593b83
Author: Pauli <paul.dale at oracle.com>
Date:   Thu Mar 9 09:42:25 2017 +1000

    Make the output of enc -ciphers identical
    
    even if run several times in a session.
    
    This amounts to moving the column counter so it isn't a function local
    static variable and reinitialising it each time.
