This is an intermediate solution for #4408. As there were no agreeed upon goals, I went with what I felt read well and that I saw commonly used on non-clap commands. - "information" isn't really a necessary word. - I originally favored `Print this help` but realied that doesn't read correctly in completions. - Besides being shorter, the reason for the flipped short/long hint is it gives people the context they need for scanning, emphasizing "summary" and "more". Fixes #4409
