Commit Message

Unai Martinez Corral March 7, 2020, 5:27 p.m. UTC 
This patch breaks backward compatibility.

Both '--persistent' and '--credential' default to 'no'. Hence, '-p no'
or '-c no' are redundant. Overall, accepting an argument might be
misleading because options are, indeed, boolean. This patch makes both
options boolean in getopt, so if any of them is provided the corresponding
variable is set to true.
