How does that not cound as an "incident"? I don't see anything in this report that relates it to `comment-use-syntax-ppss` (nor to `open-paren-in-column-0-is-defun`). > What you mean by your suggestion is to remove > open-paren-in-column-0-is-defun start altogether. No, my suggestion is to remove `comment-use-syntax-ppss` (i.e. remove the possibility to set it to nil). > Both Martin and Richard, who have less powerful machines than we do, are > unhappy about this. I don't see any reason to think their unhappiness is due to `open-paren-in-column-0-is-defun` or `comment-use-syntax-ppss`. > Anyway, what exactly happened on 2017-12-12 that qualifies as a fateful > incident?
