brew cask info should give path to resolved Cask on filesystem

[rolandwalker]

That will be straightforward after #3066.

#3066 has been merged, so replying as a reminder.

Hi,
I tried to hack something around this.

My first point is a minor question about the semantic of the Cask.installed? method. Currently it means “is this very software in this very version currently staged on this system?”. Whereas I would expect that it would mean “is this software installed on my system, whatever the version?”.
Do you guys have any plans on providing ?

Then, I looked around the .metadata directory of a cask. I realized this could be used to instantiate Cask objects that could be tested for being staged on the system. I created the PR #12746 to demonstrate the idea.

Third point, the brew cask info code states: todo completely reformat the info report.. Maybe it's time!

Cheers

Closed as #13201 will make this irrelevant
