nil
Documentation
Non-nil means Font Lock should not use syntactic fontifications.
This is normally set via font-lock-defaults. Setting it to a
non-nil value will usually cause comments and strings not to be
fontified, unless font-lock-keywords are set so as to fontify them,
or some other font-lock mechanism has the same effect even when this
variable is non-nil.
Probably introduced at or before Emacs version 19.30.
