@cindex brace in column zero and fontification
Comment and string fontification (or ``syntactic'' fontification)
relies on analysis of the syntactic structure of the buffer text. For
-the sake of speed, some modes, including C mode and Lisp mode,
-rely on a special convention: an open-parenthesis or open-brace in the
-leftmost column always defines the @w{beginning} of a defun, and is
-thus always outside any string or comment. (@xref{Left Margin
-Paren}.) If you don't follow this convention, Font Lock mode can
-misfontify the text that follows an open-parenthesis or open-brace in
-the leftmost column that is inside a string or comment.
