Command argument capitalization is a bit odd

[MJJoyce]

Our current command argument handing does its best to convert the name into a more human-readable title. This works ok but is sometimes confusing for users when our attempt at capitalization results in incorrect acronym names and the like.

E.g., psu_status -> Psu Status

We should consider alternative ways of handling the argument name and formatting. Maybe doing nothing with the name is cleaner? Or just replace _ with spaces?
