Inverse Closes colors

puts ANSI.yellow{ "Foo" + ANSI.invert{ "∙∙∙" } + "bar" }

You can see the bar at the end isn't yellow, but you'd expect it to be. I'm using invert to make whitespace visible in a text based game.

The actual output is:

"\e[33mFoo\e[7m∙∙∙\e[0mbar\e[0m"

Expected:

- "\e[33mFoo\e[7m∙∙∙\e[0mbar\e[0m"
+ "\e[33mFoo\e[7m∙∙∙\e[27mbar\e[0m"

I tried adding a test case, but they don't appear to be passing right now when I run rake test.

  method :invert do
    test do
      str = ANSI::Code.invert
      out = "\e[7m"
      out.assert == str
    end

    test "with block notation" do
      str = ANSI::Code.invert { "World" }
      out = "\e[7mWorld\e[27m"
      out.assert == str
    end
  end
