* Factor out the default `MultiCommand` behavior All the `MultiCommand`s had (nearly) the same behavior when called without a subcommand. Factor out this behavior into the `NixMultiCommand` class. * Display the list of available subcommands when none is specified Whenever a user runs a command that excepts a subcommand, add the list of available subcommands to the error message. * Print the multi-command lists as Markdown lists This takes more screen real estate, but is also much more readable than a comma-separated list
