Why is RunBackgroundShell() replacing ouputs with less than 3 lines?

Problem

If I use run <sh-command> if the output is less than 3 lines, it will be overridden by "... exited with/without error" So I have to add unnecessary newlines to my command's output just to be able to see it.

The culprit is the line I have highlighted in the file internal/shell/shell.go here:

func RunBackgroundShell(input string) (func() string, error) {
	args, err := shellquote.Split(input)
	if err != nil {
		return nil, err
	}
	if len(args) == 0 {
		return nil, errors.New("No arguments")
	}
	inputCmd := args[0]
	return func() string {
		output, err := RunCommand(input)
		totalLines := strings.Split(output, "\n")

		str := output
		if len(totalLines) < 3 {   // <<<<<<<<< HERE
			if err == nil {
				str = fmt.Sprint(inputCmd, " exited without error")
			} else {
				str = fmt.Sprint(inputCmd, " exited with error: ", err, ": ", output)
			}
		}
		return str
	}, nil
}

Why is that line there?
