This removes the logic to automatically add [OPTIONS] to the usage output. The current logic was broken if a command only has deprecated or hidden flags, and in many cases put the [OPTIONS] in the wrong location. Requiring the usage string to be set manually gives more predictable results, and shouldn't require much to maintain. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
