Add the --help command-line flag. #247

Wait, I just realized that we're already using the -h flag to disable highlighting. I'll just make it --help and help.

Since help is not a flag that modifies other operations, but instead a subcommand that does something entirely different, I think the existing version is more correct.

That's fair, but --help is basically a standard among Unix CLI applications, so I don't think adding it hurts.
