confusing helptext

[lolbinarycat]

several UX problems:

• "review" and "verify" are very similarly named, and the helptext doesn't really disambiguate. "write" and "check" would be more clear.
• additionally, to actually do code review, you use "open", not "review".
• also, the initial help messages for these commands just say they are aliases of crate commands, so you have to run another help command to get at the actual helptext.

most of the auxilary commands like crate dir have fairly clear helptext.. but for some reason the core 3 don't really.
