Since you told me you weren't going to fix the problem I had
identified, I had no reason to look at CHANGES or to reread the
manual.

Now I see 'rl_pending_signal()' and 'rl_persistent_signal_handlers' -
thank you!

Can you add an example that demonstrates how to use the new variable
and function to get good (bash-like) behavior on SIGWINCH and SIGINT?
Or should I put this on my own (long) TODO-list?

Thank you,

Frederick
