Just to remind people, I fixed all this nonsense about parens in column
0 and `open-paren-in-column-0-is-defun-start' over a year ago.  Key
search term: "comment-cache".

My fix was rejected without any deep, soul-searching consideration, for
reasons which appeared obscure then and haven't become any clearer
since.

This bug, the failure to deal reasonably with open parens in column
zero, is a malignancy on the face of Emacs, breeding bug after bug after
bug, as we see here, as we have seen many times over the years.

If my fix isn't going to be accepted, I think it's high time that
somebody else stepped up to the plate and fixed this monstrosity once
and for all.
