--help, help, and lab/git are all inconsistent about lab

Thanks for reporting, will get a fix up for this today or tomorrow. I'm definitely guilting of missing some edge cases that fall outside my workflow so I really appreciate the report

This is a little trickier than I thought it would be. It requires hacking around cobras built in help functionality. I managed to get the help output consistent and in the process broke all of lab's help functionality. I'll need to put in some extra logic to properly execute the wrapped help when appropriate and keep lab's help intact.

I think the above #108 addresses all of the issues here. It deserves some thorough tests and review given the borderline hacks required to make this work with cobra. Should be able to get tests in place this weekend and planning to upgrade cobra to see if anything in a newer version that can be put to use.

Fixed in #108 will go out in 0.9.5
