[issue24266] raw_input + readline: Ctrl+C during search breaks readline

[Martin Panter]

Martin Panter added the comment:

Readline 7.0 alpha version includes a new “feature” that should help:

i.  rl_callback_sigcleanup: a new application function that can clean up and unset any state set by readline’s callback mode.  Intended to be used after a signal.

Patch readline-sigcleanup.patch uses this function, depending on a compile-time version check. It fixes the bug when compiled against Readline 7.
