Yuya Nishihara 31525705db cli: add "Hint: " or "Warning: " heading to almost all messages 
It's inconsistent that some warnings have headings and some don't, and it seems
the choice is arbitrary. Let's unify the style. There are two exceptions:
1. continued line following labeled message,
2. "unrecognized response" followed by prompt.
