In Emacs commit f596f0db82c0b1ff3fe8e8f1d8b07d2fe7504ab6, from Nov 2021,
the function `indent-according-to-mode' was given an optional
inhibit-widen argument. That argument being passed causes orgalist's
advice to fail, as the lambda doesn't accept any additional arguments.
One way to fix it would be like that:
(unless (advice-member-p 'orgalist-fix-bug:31361 'indent-according-to-mode)
(advice-add 'indent-according-to-mode
:around (lambda (old &optional inhibit-widen)
"Workaround bug#31361."
(or (orgalist--indent-line)
(let ((indent-line-function
(advice--cd*r indent-line-function)))
(funcall old inhibit-widen))))
'((name . orgalist-fix-bug:31361)))))
Or I suppose a more future-proof approach might be to use a &rest and
then `apply' instead of `funcall'.

A better solution would probably be to fix this without using
add-advice. While advice can be a useful escape hatch, it really is best
avoided, especially given that it doesn't always play nice with lexical
binding. I note this one is also calling an undocumented internal
function.

In principle I quite agree! But orgalist is basically built on top of
add-function/advice-add, so I didn't think that was an option. And
also assumed that, given what Orgalist is trying to do, there isn't a
cleaner solution right now.

What do you think, Nicolas? Can I patch this to use &rest and `apply'?
