[Request] Support brew cask install {user}/{tap}/{formula}

[sonots]

This is a feature request.

brew install is currently supporting install manner like

brew install homebrew/versions/gcc45

instead of

brew tap homebrew/versions
brew install gcc45

This is useful especially in Brewfile because executing brew tap twice raises Error: Already tapped and stops brew bundle with the current homebrew. They (homebrew guy) are recommending to use brew install {user}/{tap}/{formula} manner to avoid the problem (brew install does not raise Error, but raises just Warning if already installed, so it does not stop brew bundle).

I am sending another feature request to homebrew so that brew tap raises Warning rather than Error at Homebrew/legacy-homebrew#25511, but I am very happy if brew cask install would also support brew cask install {user}/{tap}/{formula} manner.

Check out #2085. A sample Caskfile is here: https://github.com/pstadler/dotfiles/blob/master/Caskfile

This should be go into some readme/doc?

Btw: we should not close this issue. If it is a functionality from brew install to accept a {user}/{tap} in path, then brew cask install should be the same functionality.

Okay, I reopened.
