Thanks, but I have all that already working (I'm using liboop for the
asynchronous I/O and it has a readline adapter). My question is not
about I/O, only about display.

I have tried with rl_message and it works as long as the prompt is on
a single line but the display seems to get messed up with prompts
spanning multiple rows. Specifically, I have tried:
rl_save_prompt();
rl_message("%s", text);
rl_restore_prompt();
rl_clear_message();

I would like to avoid fiddling on the low level if possible. Is there
no way to do this otherwise?
