If my understanding is correct, the "set xterm title” thing works right now, because
prompt_print just passes the escape sequences through uninterpreted.

We can probably parse them, why not? But I agree that construction should
be terminal independent.

So what about parsing escape sequences in the prompt? We can extract sequences
dealing with text presentation and let the remaining ones pass through as it is currently
done.
