Thank you, Rasmus, that's very helpful.
Indeed, what I plan to do now is revert to the old behaviour on col 0,
which should address this case as well as other cases mentioned here.
Regardless of anything else, I agree this is the right thing to do on
col 0.

Thanks for this clarification too.

“C-o at the middle of the line” is what my patch was meant to address
(the above effect was an accident). In this situation, if the
indentation engine works correctly, the old behaviour is something I
don’t think would ever be useful. That’s what motivated the change.

When the indentation engine does not work correctly, then my patch
doesn’t make things better, but I guess it doesn’t make them worse
either.

The complexity here is very manageable, and the function isn’t long.
Besides, it’s a very frequently used command. It’s worth investing and
extra 4 or 5 lines to make it more natural.
