test failures with octave 7.1

The Fedora python-octave-kernel package fails to build with the following test failure with octave 7.1:

This is with jupyter-kernel-test 0.4.3.

I believe this is the same issue as https://github.com/kislyuk/argcomplete/issues/337#issuecomment-771835184

Yes, it is the same issue, but the change in metakernel above does not fix it.

I have the same problem on Ubuntu 22.04 with Octave 7.2.0, as well. My metakernel 0.29.4, contains the proposed fix. I could not figure out, why it does not actually fix it.

However, as a workaround, I added set enable-bracketed-paste off in my ~/.inputrc (according to https://savannah.gnu.org/bugs/?54335#comment3 this disables bracketed paste in octave). This works for me, but it might affect other applications as well. I have not encountered any problems, yet.
