### Problem / Steps to reproduce

I'd just like a way to see colors for matches, similar to grep


Start at the --filter entry point and trace how fzf currently formats filtered output. Compare the requested behavior with grep's colorized matches and define the expected output and terminal conditions before implementation; done means the behavior is documented and covered for the relevant --filter cases.
