+Each element in a user-level keywords list should have one of these forms:
MATCHER
(MATCHER . MATCH)

+call to make the search (called with one argument, the limit of the search;
+it should return non-nil, move point, and set `match-data' appropriately iff

MATCHER regexps can be generated via the function `regexp-opt'.
FORM is an expression, whose value should be a keyword element, evaluated when
This variable is set by major modes via the variable `font-lock-defaults'.
Be careful when composing regexps for this list; a poorly written pattern can
-dramatically slow things down!")

-KEYWORDS may be a symbol (a variable or function whose value is the keywords to
-use for fontification) or a list of symbols. If KEYWORDS-ONLY is non-nil,
-syntactic fontification (strings and comments) is not performed.
-If CASE-FOLD is non-nil, the case of the keywords is ignored when fontifying.
-If SYNTAX-ALIST is non-nil, it should be a list of cons pairs of the form
-\(CHAR-OR-STRING . STRING) used to set the local Font Lock syntax table, for
-keyword and syntactic fontification (see `modify-syntax-entry').
-
-If SYNTAX-BEGIN is non-nil, it should be a function with no args used to move
-backwards outside any enclosing syntactic block, for syntactic fontification.
-Typical values are `beginning-of-line' (i.e., the start of the line is known to
-be outside a syntactic block), or `beginning-of-defun' for programming modes or
-`backward-paragraph' for textual modes (i.e., the mode-dependent function is

-These item elements are used by Font Lock mode to set the variables

-Further item elements are alists of the form (VARIABLE . VALUE) and are in no

-;;; Global Font Lock mode.
-
-;; A few people have hassled in the past for a way to make it easier to turn on
-;; Font Lock mode, without the user needing to know for which modes s/he has to
-;; turn it on, perhaps the same way hilit19.el/hl319.el does. I've always
-;; balked at that way, as I see it as just re-moulding the same problem in
-;; another form. That is; some person would still have to keep track of which
-;; modes (which may not even be distributed with Emacs) support Font Lock mode.
-;; The list would always be out of date. And that person might have to be me.
-
-;; Implementation.
-;;
-;; In a previous discussion the following hack came to mind. It is a gross
-;; hack, but it generally works. We use the convention that major modes start
-;; by calling the function `kill-all-local-variables', which in turn runs
-;; functions on the hook variable `change-major-mode-hook'. We attach our
-;; function `font-lock-change-major-mode' to that hook. Of course, when this
-;; hook is run, the major mode is in the process of being changed and we do not
-;; know what the final major mode will be. So, `font-lock-change-major-mode'
-;; only (a) notes the name of the current buffer, and (b) adds our function
-;; `turn-on-font-lock-if-enabled' to the hook variables `find-file-hooks' and
-;; `post-command-hook' (for buffers that are not visiting files). By the time
-;; the functions on the first of these hooks to be run are run, the new major
-;; mode is assumed to be in place. This way we get a Font Lock function run
-;; when a major mode is turned on, without knowing major modes or their hooks.
-;;
-;; Naturally this requires that (a) major modes run `kill-all-local-variables',
-;; as they are supposed to do, and (b) the major mode is in place after the
-;; file is visited or the command that ran `kill-all-local-variables' has
-;; finished, whichever the sooner. Arguably, any major mode that does not
-;; follow the convension (a) is broken, and I can't think of any reason why (b)
-;; would not be met (except `gnudoit' on non-files). However, it is not clean.
-;;
-;; Probably the cleanest solution is to have each major mode function run some
-;; hook, e.g., `major-mode-hook', but maybe implementing that change is
-;; impractical. I am personally against making `setq' a macro or be advised,
-;; or have a special function such as `set-major-mode', but maybe someone can
-;; come up with another solution?
-
-;; User interface.
-;;
-;; Although Global Font Lock mode is a pseudo-mode, I think that the user
-;; interface should conform to the usual Emacs convention for modes, i.e., a
-;; command to toggle the feature (`global-font-lock-mode') with a variable for
-;; finer control of the mode's behaviour (`font-lock-global-modes').
-;;
-;; The feature should not be enabled by loading font-lock.el, since other
-;; mechanisms for turning on Font Lock mode, such as M-x font-lock-mode RET or
-;; (add-hook 'c-mode-hook 'turn-on-font-lock), would cause Font Lock mode to be
-;; turned on everywhere. That would not be intuitive or informative because
-;; loading a file tells you nothing about the feature or how to control it. It
-;; would also be contrary to the Principle of Least Surprise. sm.
