@zappolowski How is this for you? (in re: tmux-python/tmuxp#844)

Do any tests fail w/ libtmux?

[zappolowski]

It's still the doctest from src/libtmux/pane.py:159 which fails. That test also seems a bit flaky as the captured value either is empty [] or (as mentioned somewhere else) the default prompt of bash which is PS1=\s-\v$ and thus ['sh-5.1$'].

I still have no clue how this issue could be resolved, but as already stated its easy to ignore for humans - as long as the CI uses dash it won't fail.

[tony]

I will take care of it - but I don't have an ETA yet (until I understand it better / reproduce it reliably)

@zappolowski Moved this to #456 so it has a dedicated issue
