Originally, some of the commands' usage display didn't achieved to show newline, while some of them does, which are more user-friendly, and won't confuse the message if there're more which should be in the nextline. Fix this issue by returning usage string with a newline. Signed-off-by: I Hsin Cheng <[email protected]>
