Re: Mysterious fontification/C++ context issue - Patch for beginning-of-defun-raw.

[martin rudalics]

To elaborate on my last mail: I think the bug is in back_comment and may
affect any mode setting `open-paren-in-column-0-is-defun-start' to nil.
My gdb is currently on strike, so could someone please try to debug
where back_comment spends its time when applying scan_lists to
syms_of_xdisp?  Maybe there's an easy solution.

Otherwise we'll have to set `open-paren-in-column-0-is-defun-start' to t
in C mode until someone fixes this.
