To help us debug your issue please explain:

• What you were trying to do (and why)
  Run brew info r (on a clean Debian or Ubuntu Docker image from linuxbrew/docker)

• What happened (include command output)

Error: No available formula with the name "linuxbrew/xorg/xorg"

• What you expected to happen
  For the :x11 requirement to be displayed in the brew info output

• Step-by-step reproduction instructions (by running brew commands)
  brew info r (or some other formula that has a :x11 requirement)

It's possible to resolve this issue by tapping linuxbrew/xorg instead of display the message Error: No available formula with the name "linuxbrew/xorg/xorg". That behaviour would be different though than upstream Homebrew/brew. It could possibly be a warning instead of an error. Linuxbrew installer could tap linuxbrew/xorg by default. Any other ideas?

I personally think tapping it in the installer is a good idea.

I'm happy with that solution if you'd like to submit a PR.
