perforce plugin: 1.3.18
jenkins: 1.484

I use AD for authentication, so I have my own authentication script on the perforce server. A "p4 login -a -p" prints

Success: Password Verified.
<THE_TOKEN_FROM_PERFORCE>

As of 1.3.18 the plugin tries to use "p4 -P "Success: Password verified." workspace -o ...." instead of using <THE_TOKEN_FROM_PERFORCE>

I can change my authentication script to not print this on my server, but I also have to use another perforce server that I'm not in control of, they print other things, so I'm not sure I can get them to change that. Prior versions of this plugin didn't have this issue.
