OK, you've convinced me.  I now agree with you that CC Mode should not
itself set that horrible variable to nil, not even as a default.  I
should remove the offending line from cc-mode.el, and put some extra
explanation into cc-mode.texi and programs.texi.

Users may well want something like this in their c-mode-common-hook:

(if (< (- (point-max) (point-min)) 100000)
  (setq open-paren-in-column-0-is-defun-start nil))

, so the implemention of opic0ids code in beginning-of-defun-raw should
stay, IMAO.

Another possibility would be a new option in CC Mode (probably
implemented as a Clean-Up), which would guard against rogue (s and {s in
column 0.  Were this to be switched on, c-electric-paren,
c-electric-brace, and the filling routines would insert a \ at column 0
when needed.

The available evidence is that hackers cannot be expected to notice and
correct these things without help.
