Thanks for the reference, it explains the problem. But this is a very strange logic. I don't get it. Why it depends on the presence of the ellipsis and fails without it? Now I see this bug report is a duplicate of bug#56837. This is a problem because modes use 'current-indentation' to get an outline level in 'outline-level' function, e.g. (setq-local outline-level (lambda () "`outline-level' function for Python mode." (1+ (/ (current-indentation) python-indent-offset)))) (setq-local outline-level (lambda () (1+ (/ (current-indentation) ruby-indent-level)))) But this fails when users want to remove an ellipsis.
