Migration Tips
If you use .on('command:*') or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
If you use program.args or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
If you use .command('*') to add a default command, you may be be able to switch to isDefault:true with a named command.
If you want to continue combining short options with optional values as though they were boolean flags, set combineFlagAndOptionalValue(false) to expand -fb to -f -b rather than -f b.
