Allow customising of "extra" help

[donaldpipowitch]

When I use certain things like choices or default values the outputted help looks quite convoluted to me. It would be nice to optionally hide that output of format it differently.

E.g. I have this:

Options:
  -l, --log-level  Set log level
      [choices: "silly", "verbose", "info", "warn", "error", "silent"] [default:
                                                                         "info"]
  -v, --version    Show version number                                 [boolean]
  -h, --help       Show help                                           [boolean]

Maybe something like this is nicer:

Options:
  -l, --log-level  Set log level (default: "info")
                   [ "silly", "verbose", "info", "warn", "error", "silent" ]
  -v, --version    Show version number                                 [boolean]
  -h, --help       Show help                                           [boolean]

Options:
  -l, --log-level  Set log level (defaults to "info" or use "silly", "verbose", "warn", "error", "silent")
  -v, --version    Show version number                                 [boolean]
  -h, --help       Show help                                           [boolean]

Options:
  -l, --log-level  Set log level (defaults to "info")
  -v, --version    Show version number                                 [boolean]
  -h, --help       Show help                                           [boolean]

Options:
  -l, --log-level  Set log level (info,silly,verbose,warn,error,silent)
  -v, --version    Show version number                                 [boolean]
  -h, --help       Show help                                           [boolean]

@donaldpipowitch I am really liking your suggestions! A more readable version is always 💯 for me.

This could work as a verbose version for our help output, for sure.

exactly, the choices line is too long to read, why not break them into different lines to make our eyes feel better?
