refactor how to assign only whether :formula or :cask in commands like cmd/fetch.rb.

Nice refactor! Perhaps in cases where only is used once then args.only_path_formula_or_cask could be passed as a parameter directly?

Thank you for the advice. I will change only into args.only_path_formula_or_cask

[reitermarkus]

Suggested change

	def only_path_formula_or_cask
	def only_formula_or_cask

Not sure why path should be in the name.

[reitermarkus]

Given that all of these are passed from Args to NamedArgs which already contains a reference to Args (self.parent), we could just set the default value on the methods themselves, e.g.

def to_paths(only: self.parent&.only_formula_or_cask)

Thanks again @hyuraku!
