After looking through font-core.el for several seconds, I don't have any
idea, either, what this is supposed to mean. This is the full text:
The previous version was:
-Specify this variable using @var{other-vars} in
@code{font-lock-defaults}.
and
-Major modes normally set this variable with @var{other-vars} in
-@code{font-lock-defaults}.
but vc-region-history on the doc string of that variable seems to say
that it has never talked about "other-vars".
Anybody want to take a guess at what this is supposed to mean?
-- Variable: font-lock-syntactic-face-function
If this variable is non-‘nil’, it should be a function to determine
which face to use for a given syntactic element (a string or a
comment). The value is normally set through an OTHER-VARS element
in ‘font-lock-defaults’.
The function is called with one argument, the parse state at point
returned by ‘parse-partial-sexp’, and should return a face. The
default value returns ‘font-lock-comment-face’ for comments and
‘font-lock-string-face’ for strings (*note Faces for Font Lock::).
