How to proberly start sub command?

[antonmedv]

Hi,

Thanks for the awesome project!

Question: how to properly start subcommand with reuse of Stdout/Stdin?

I'm doing it like so:
https://github.com/antonmedv/llama/blob/58c042eb06a5a661a1388beb4ac09cedf2764ad0/main.go#L183-L190

func (m *model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
	if m.editMode {
		return m, nil
	}

				cmd := exec.Command(lookup([]string{"LLAMA_EDITOR", "EDITOR"}, "less"), filepath.Join(m.path, m.cursorFileName()))
				cmd.Stdin = os.Stdin
				cmd.Stdout = os.Stdout
				// Note: no Stderr as redirect `llama 2> /tmp/path` can be used.
				m.editMode = true
				_ = cmd.Run()
				m.editMode = false
				return m, tea.HideCursor

But what to do if a redraw is needed after cmd exits? And is there a better way to halt the program until cmd is exited?

Thanks.
