bug#17730: 24.4.50; (elisp) `Syntactic Font Lock': undescribed OTHER-VARS

[Drew Adams <drew.adams@oracle.com>]

The doc refers to "an OTHER-VARS element in `font-lock-defaults':

 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'.

Incomprehensible.  There is no "an OTHER-VARS element" described
anywhere in the doc of `font-lock-defaults' or in the link in the next
paragraph (node `Faces for Font Lock').

And there is no "OTHER-VARS" anywhere in the Emacs Lisp code, other than
a presumably unrelated (and just as undescribed) occurrence in pcase.el.
