I rebased and force-pushed now that #24110 has been merged to fix the broken docs so that CI will pass on this PR.

This PR is stale because it has been open for 30 days with no activity.

(in response to stale label) This issue still exists in Python so the PR is relevant.

I'll test this.

In the meantime, could you please explain why is the addition needed at two different places? Thanks.

(Note that I am not familiar with readline or the way Python uses it, I'm just the Fedora Python maintainer who saw your email on the python-dev list and realized that this also affects Fedora because we have updated as well and I've already been hit by that.)

I've applied this patch to Python 3.9.1 in Fedora Rawhide. This fixes the problem.

Before:

Python 3.9.1 (default, Jan 27 2021, 00:00:00) 
[GCC 11.0.0 20210123 (Red Hat 11.0.0-0)] on linux
Type "help", "copyright", "credits" or "license" for more information.

       ^
SyntaxError: multiple statements found while compiling a single statement

After:

Python 3.9.1 (default, Jan 27 2021, 00:00:00) 
[GCC 11.0.0 20210210 (Red Hat 11.0.0-0)] on linux

The setting needs to be disabled after each call to rl_read_init_file in case a user manually has enabled bracketed paste within their inputrc file.

One is for when read_init_file is called from Python and the other is part of the module initialization.

Nope, I'm good. Thanks

Label it with the backport labels for miss Islington maybe?
