‘--help’ recursively refers to itself

[kseistrup]

The help in v0.33.1 is a little confusing:

$ toot -h      # just guessing that ‘-h’ will show some help
Unknown command '-h'
Run toot --help to show a list of available commands.
$ toot --help  # let's try the suggestion
Unknown command '--help'
Run toot --help to show a list of available commands.

However, an empty “command” will do the trick:

$ toot '' --help
toot - a Mastodon CLI client
v0.33.1

Authentication:
  toot login            Log into a mastodon instance using your browser (recommended)
  toot login_cli        Log in from the console, does NOT support two factor authentication
    ⋮

b8f49ef adds support for toot --help.

I plan a refactor which will improve this further, but this is a quick fix for now.
