got help tag text is a little confusing due to duplicate -a options

[jscook]

got help tag has two '-a' options. One is an option to 'got' and another is an option to 'got tag'.

The help text does not immediately show this.

I tried to find a simple work around but I was not able to find anything simple in App::GitGot or App::Cmd. The 'global options' portion of App::Cmd looked interesting though.
