Yeah, you should look at the actual documentation.  Not only does it
explain the situation, readline-7.0 adds a variable that restores the
previous persistent signal handling behavior if the application desires.
That reduces the `undocumented sequence' to one line of code.

If you're not going to read the documentation, or at least the new feature
descriptions in the CHANGES file, there's not a lot I can do to help.

The example still exits on SIGINT, as most programs do.
