You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: hint.go
    path of file: ./repos/sliver/vendor/github.com/reeflective/readline/internal/completion
    
    the code of the file until where you have to start completion: package completion

import (
	"strings"

	"github.com/reeflective/readline/internal/color"
	"github.com/reeflective/readline/internal/term"
)

	hint := ""

	// First add the command/flag usage string if any,
	// and only if we don't have completions.
	if len(comps.values) == 0 || e.config.GetBool("usage-hint-always") {
		if comps.Usage != "" {
			hint += color.Dim + comps.Usage + color.Reset + term.NewlineReturn
		}
	}

	// Add application-specific messages.
	// There is full support for color in them, but in case those messages
	// don't include any, we tame the color a little bit first, like hints.

	messages = strings.TrimSuffix(messages, term.NewlineReturn)

	if messages != "" {

	// If we don't have any completions, and no messages, let's say it.
