At the end, I did go into PS2="", but instead of sending script
line-by-line, I just send it once and for all outside the loop, as you
suggested. It also works and looks less fragile.

Also, I figured something called PROMPT_COMMAND, which can also
interfere with prompt. Just using PS1/2 is not always enough.
