Username syntax listed in SYNOPSIS section don't match that of OPTIONS section

I am a Couchbase qe engineer, and my test script against MH 6.5.0-2234 failed while I specify:

--user=Administrator

It has to be

--username=Administrator.

It seems tolerable for pre-6.5 releases, even though, the mismatched parameters listed in synopsis section and options section can confuse users.

screenshot attached.

Another suggestion, I think synopsis should list both short and long form of options such as [-c | --cluster <url>] or something like this.
